I rarely comment but here I have to. I am an engineering student and I have to finish this assessment for next week, part of the assessment is to design an inverter that is connecting a solar pannel to AC loads. I must confess that until now I only had a vague idea of what an inverter is, but with this video I finally have a complete understanding of the working of such a device. Power electronics is clearly not my favorite course but at least you have made it comprehensible, thank you very much.

@@svwtsvfcbIn a round about way he's condemning higher education systems that put a focus on teaching global warming or simularly gender or racial equity rather than a focus on engineering principles students need to understand what they are working on or with, and the low bar of useful education students recieve. I don't know how far you're into your education, and neither does the previous commentator. But if you're just beginning your degree, then I'd say there's no big sign of a problem yet. But if you're near finishing your degree and you're just comming to understand an inverter, then maybe you should question your school and how messed up it is that people and you spend gobs and gobs of money for useless information that benefits neither the students, nor their future employers, nor their employer's customers, nor socity in general. Instead you're saddled with massive debt and foreigners take your job opportunities because you're not well qualified. That's politely pretty much the intention behind the previous commentator. While I pretty much agree with that generally about the average student, I'm glad you're seeking out information and found this video helpful. And I hope that you focus on education that helps you better satisfy people's needs through your engineering degree. And I hope that putting those skills to use benefits you financially and those who you help, or are helped by your work. 😊

In building my first electric car, this has been super helpful. I'd like to know more about the current load relationship between source voltage DC into the motor controller vs motor controller output after converted to 3 phase. I can easily get motor specs however I need to spec connections to the battery packs. Most connectors I find are rated at a far lower ampacity than I'm dealing with while utilizing a much larger conductor. 90mm2 vs my 50mm2 that was included with the supplied parts. Thanks again for making these videos very helpful and clearly laid out.
@evertadams3628 2 роки тому
Very good for the basics of an inverter. Personally I used to startup AC variable speed inverters using SCRs as switches. The trick to using SCRs is the ability to turn them off, which requires a reverse bias. The IGBT came along later. The advantage for them is that they can be turned off by removal of the trigger signal. The advent of the IGBT significantly reduced the cost of the inverter and or AC variable speed drive. Note that all inverters wither AC or DC sourced, have a constant voltage DC Buss dependent on the value of the input voltage.. The DC buss voltage results in a constant Peak to Peak voltage. The pulse width modulation as described in this articular is used to vary both the frequency of the output as well as the output RMS (effective) voltage. When used for variable speed when powering an AC motor, constant torgue is maintained by keeping the ratio of the frequency to the RMS voltage constant. For a 460 VAC to 60 hertz system this ratio is 7.67 V/hz. Once the motor rated speed from a constant voltage/frequency system is reached, the motor speed can still be increased by just increasing the frequency with no further increase in voltage. This is called the constant horsepower range. Their is a limit to this as the torque decreases to a point where the motor will no longer run. An inverter and or AC variable speed drive with a 3 phase output has another advantage in that the motor rotational direction can be reversed by just reversing the phase sequence as controlled by the triggering sequence of the IGBTs.
@mikechiodetti4482 2 роки тому
I remember learning this in some electronics courses. The Toyota Prius hybrid had been using LARGE IGBT's for it's 3 phase motor. Napa Auto Parts training side had a fantastic course explaining how it all worked and more that was built into the system. Of course this video answers questions much better than the books I've read, and I thank you for this. If anyone is learning about DC to DC and DC to AC inverters and converters. That Napa course will give a lot of info, but this video is the start! I'm assuming people that see this video understand the basic theory that "When magnetic lines of force cut across a conductor, a voltage is induced in the conductor and current (electrons) can flow." Without this "working theory," we'd never have the great electrical and electronics we have now!

@ulrikcaspersen9145 3 роки тому
Great video and explanation. One side note: Sometimes it might be difficult to get hold of a 3-phase inverter or an inverter capable of outputting the amount of power required. Therefore, some manufacturers offers inverters that can be connected in parallel to get more 2 or 3 phases instead of one, or in series to get more power (as in more Amps or Watts), or even combined in parallel and series to get perhaps 3-phases at 32 Amps instead of 3-phases at 16 Amps. But please be aware that only some manufacturers offers these solutions, and also that it is usually required that the inverters can communicate through perhaps a CAN network. Another side note: You mention inverters outputting square vawe AC and modified sine AC. Please aware that there are also som inverters which output "pure" AC; ie. with very few or no ripples and a pattern when viewed on an oscilloscape virtually indentical with what you will get from something like a wall socket. Also, some devices like certain electronics might be unstable or even be damaged if used with square vawe or modified sine AC.
@SteveWhiteDallas 2 роки тому
Yes, good advice! Also, for any viewers who don't know, there's one more thing to be aware of as the winter approaches and we face the possibility of power outages, like last winter (2021.) - AC generators (standard gasoline generators.) Be careful about what you plug into a standard AC generator. They too produce a "dirty" square wave. Televisions and any other electronic appliances that have multiple circuits with various voltages inside them will not respond well to regular AC generators. They require an Inverter Generator, which produces AC voltage, then converts it to DC voltage, then inverts it to "clean" AC voltage with a smooth sine wave (as shown in this video.)

@BloodAsp 4 роки тому
The logic of IGBT's are identical to transistors. (Not the mode of operation, but the logic.) Ie, a signal is sent to one pin, thus opening flow in one direction between the other two pins. If you want to understand how IGBT's work, start by looking at how diodes work, and understanding the quantum physics at play there, then go to transistors, then IGBT/MOSFETs.

4:13 Side note: Not all synchronous generators have a permanent magnet in their rotor. Some use a circuit fed with DC instead to produce a steady magnetic field, working as an electromagnet. 4:17 The electrons in the winding don't get pushed just because the magnet has a polarity. If that was true, holding the magnet still should also make the electrons move, since the magnet still has its polarity; but in reality this won't happen. The real reason why the electrons move is because the magnetic field of the magnet (or electromagnet) is _changing,_ thus inducing an EMF in the windings. At 4:37 you explained it correctly. 9:48 Even though the phase is split, it's still just a single phase, since the voltage or current in both live conductors are in phase (or 180° out of phase.) To be considered as two phases you'd need a phase shift between the current in the two live wires, i.e. 90°. Anyways, I understand what you meant to say. ;) 10:13 In general, the coils/windings of the generator aren't inserted 120 physical degrees (A.K.A. mechanical degrees.) In fact, in the generator you showed the angle between two adjacent coils (of different phases) is 360°/6 = 60°. Real generator have more than one winding per phase, so they're inserted at angles much less than 120 mechanical degrees; you can google about Ferrari's theorem. What is true, is the set of three output voltages are 120 electrical degrees shifted.

Sharing your channel to a discord community. We are all invested in Ozop Energy that makes a lot of the electrical components that you explain in so many of your videos! You do an excellent job, so keep it up!

The part I keep getting stuck at is *smooth* AC. Smoothing to DC with the rectifiers and a cap is fine. But, in inversion we've got PWM chopped to 'Sine-like AC' ... but it's rough. Inductors? Something clever?
@wcvp 4 роки тому
Just add the correct amount of inductance and capacitance to the output, I'm not really sure why that was left out... Makes me wonder how much important stuff like that is left out from other videos where I don't know much about the topic.

This is also a UKposts video, not a patent on how to build a nuclear powered goggle-flop flux capacitor. It's to give you a general understanding of the topic, not how to specialize your career in a specific sector of an industry.... 😂👍😝

I think more accurate PWM would be enough for most. After all many applications will work just fine with imperfect AC voltage, so they problably work with imperfect sine waves too to some point. But if for some reason we would have to have as perfect sine wave as possible, maybe we could then just run DC motors to generate AC? Definitely noticeable energy losses but it would work and wouldn't differ from power plants. :D
@jamess1787 4 роки тому
@@insoYT you can also get faster switching or "smoother" sine-wave output from decent equipment. I have Telco equipment that runs on DC and some that run on AC. We have some decent enterprise UPS' that claim 'clean sinewave' (no oscilloscope to verify). So clean that sensitive equipment doesn't complain about faults or dirty generator power when we have to cutover.
@wcvp 4 роки тому
James S I agree, it is just a UKposts video to give general understanding. What I don’t like is that the video makes it seem like, yes this all you need to do to make the output identical to traditional AC generation. I wouldn’t care if it was just a mention of “this is close enough for nearly all applications, but it’s not exactly the same”

I came here for a review of inverters but instead got a course on electricity. They finally got to my interest in minute 6. I always wanted to find someone to explain my modified sine wave inverter vs my full sine wave inverter. Thanks

How does the controller work that times the opening and closing of the transistors?
@pasticcinideliziosi1259 3 роки тому
computers and controllers are basically calculators, they do these types of calculations way faster when you load a video or play videogames

Youre experiencing the dunning kruger effect* (or however you spell it). Youre going towards the pit of confidence but dont worry after you pass that pit, your confidence will increase with the increase of knowledge. If you dont know about this, i'll try to explain it the way i understand it. they (dunning and kruger) observed how people with different levels of knowledge displayed confidence. People with no knowledge had no confidence, people with (overall) little knowledge had a lot of confidence (i get to explain this a bit later). people with with moderate knowledge had a lot of doubt. And the experts had a lot of confidence. The graph kinda looks like this _/V. As people start learning about something their scope of the overall knowledge starts out small so they believe they have conquered a high percentage of all knowledge to be had. That is until they realize that there is a whole lot more to what they do not know, thats when their confidence start to fall. And it will fall more and more until they have the full scope of the knowledge to be had. Kinda like moving the goal post further and further until it doesnt move anymore. And as they continue to learn, they get closer to the goal and that builds confidence.

This is one of the best videos on the subject! Only, at 4:33 I think we are giving the wrong impression with the magnets and electron relationship. I believe it is the moving magnetic field that causes electrons to flow and not the 'attraction' of the magnets 'pulling' and 'pushing' the electrons. Perhaps you felt that by saying 'pushing' and 'pulling' it would adequately cover the point allowing you to move forward to the other, more important and relevant-to-the-video ones. All-in-all, I found this very helpful. Thanks.

I was building a air compressor for the home. I needed a head pressure relife switch. I only had a D C shuttle air switch to use. I put a diode inline with the 110 volt input and it worked.

Wow amazing video. I’ve been trying to figure this out but this makes it less complicated. I do have a question. What decides when the IGBTs open/close? Like to choose how fast/slow they open/close.

It is not gaps ... there is power .. take the V square ... but the power signal has gaps, not the voltage signal so we fill these gaps by other phases power
@Hopeless_and_Forlorn 3 роки тому
There are power gaps in single-phase ac. Any instant that either voltage or current is zero, power is zero.

Are solar golf carts as bad of an idea as I believe it is a good idea? It seems like a better way to make sure you are off the course before dark and maybe save a golf course some electricity bill by leaving solar carts outside the cart barn where they usually get plugged into to charge for a full day of tee times
@l0nk267 Рік тому
