It couldn't have been done better and so well explained. It is just what I was looking for. My intention is to recycle microwave transformers using the 220v input and replace only the 2kv output coil with a 12v one to use it in reverse and get the 1000w in this project. I like that the project uses a single coil transformer with no midpoint, which makes it easier to wind. Thanks for sharing your excellent work. Greetings from Argentina!

I made a 300 watt inverter from a KIT many moons ago. It did not feature a pure sinewave ouput, infact not even a modified sinewave! - its output was a square wave at 50Hz | 240VAC RMS. It powered incandescent lights, CRT televisions, arcade game machines and computers. In fact this was so long ago that the common man did not know what an inverter was. Everyone that saw my toy wanted to buy it!!! I used to use it t ok power computers at a flea market to show people that the computers work, increasing my chances of a sale. Many people said to me "how much for the box powering the computer?" I used car batteries as the DC source, but I do of course realize now that deep cycle SLAs are the more appropriate choice of battery to use. Thanks for a great video friend. 5☆ quality - you are a genius.

I'll be updating this pinned post often: - The setup itself isn't 1000W overall, the board on the other hand can handle 1kVA transformers, if connected to a proper transformer it should achieve 1kW. - Still waiting for the 1kVA UPS transformer I ordered. - The design was from the suggested schematic on the application notes with reference to 1kW EGS002 kit boards from forums. - MOSFETs were connected in parallel to reduce on-resistance and distribute the heat. - A larger heatsink may be required for larger transformer setups. - Please wait for part 2. Revisions have to be done on the board to work universally with inputs up to 80VDC. I prefer higher voltage variants as line traces would be able to accomodate the currents as currents are lower on higher voltage setups. TVS diodes were added on version 2 to suppress trancients. An XL7005A was added to feed the gate drive and a 78M05 for the logic supply. - A suggestion was made on adding an inductor along the line to reduce the not so good standby current this current version has.

Can you also measure the efficiency of your design? I think its better id you add a reverse voltage protection (using a Mosfet) and an inrush current limiter (maybe using LTC7004) to prevent sparking due to high inrush because of your tank capacitor in your input side. Here's the link you can use for reverse polarity protection using mosfet. www.google.com/url?sa=t&source=web&rct=j&url=www.infineon.com/dgdl/Reverse-Batery-Protection-Rev2.pdf%3FfileId%3Ddb3a304412b407950112b41887722615&ved=2ahUKEwiNmKCUgoLtAhXQfd4KHV6RATwQFjAPegQIDRAB&usg=AOvVaw2eSUGgd99Sukx99QiUQxRf

Wow, excellent project and lots of complete info and explanations. Waiting for next episodes. I guess it would be too current demanding on de DC side, I was thinking about an alternative to run from 24 or 48VDC so we could increase the output power provided we could get a transformer up to the task. But many circuits such as 7805 and egs002 don't seem to work above 15v, and probably some others components too. Hope you could built a very high power version that's competitive in price comparing the very expensive sine waves inverters on sale.

I have to point out that many (maybe most) film type capacitors can have a very short life when they are connected across AC power at “mains” voltage levels. I recommend that you find capacitors for that function that are specifically rated for the AC voltage level AND that carry markings showing that they comply with the various international safety agencies; such capacitors are intended to operate in this particular manner. Those capacitors that only have a DC voltage rating (the default voltage rating type is DC when AC is not specified) don’t ever get subjected to very high AC currents, but the AC currents across a power line are unpredictable and can be high if high frequency interference sources are plugged in.
@voiceofinsight5811 Рік тому
Hi, I find your comment very interesting, is this applicable to all the listed capacitors used here for this build, i.e., - 470nF 25v Capacitor - 2.2uF +350v Capacitor - 2.2uF 25v Capacitor - 10uF 25v Capacitor - 100uF 25v Capacitor
@stevebabiak6997 Рік тому
@@voiceofinsight5811 - the 25V capacitors aren’t seeing the full AC mains voltage. Capacitors that are placed in a circuit that exposes them to the AC mains should have safety agency approval markings showing that they have been examined and determined to be suitable for such use.

@@stevebabiak6997 Thanks for this clarification. Can the capacity of this build be increased to 2 kW only by increasing the transformer capacity to a 2 kW transformer or does any other component need to be changed, and, is the transformer ratio 7V:220V or 12V:220V.
@stevebabiak6997 Рік тому
@@voiceofinsight5811 - I did not design this circuit, so I can’t be 100%. We don’t know the transformer power capability; if it isn’t capable of 2kW then you would have to identify one that can handle that much power (and I would find one with a 20% margin, so maybe 2.5kW). Next the power output semiconductors have to be evaluated to see whether they could drive the additional power demand that will be present. Larger heat sinks might be needed. Higher power MOSFETs might be needed. If you aren’t able to figure out all of that, you might be better off just buying something pre-built to deliver the power you seek. And safety agency approval is quite likely going to come with that pre-built unit, something that the DIY version won’t have. If something hazardous occurs (a fire or electric shock injury for example), any insurance company is going to look for safety agency approval.

0:36 Desktop computers are technically DC appliances. Internally they require only a source of 12V, 5V & 3V DC. Not being pedantic, i mention it coz you can get pure DC power supplies for computers (require only a 12V DC input) and i think they're a really good idea. Wish i saw more of them. They're probably really good for making your own UPS for your PC too - coz there's no need for an inverter, you just keep it DC the whole time, thus adding batteries into the mix is easy.

That's actually in my list of power electronics video tutorials in 2021. "Converting AC Appliances To DC" It's a brief tutorial on how to bypass the AC-DC portion frim devices, add connectors and proper switching regulators. This way you don't get to lose power from the typical DC-AC AC-DC convertion process from the typical PV setups. I'm also planning to build a proprietary plug for my workspace that acarries the 220VAC grid line and 48VDC directly from my battery & BMS. As for the PSU to inverter, it's not a bad idea!

Amazing! Dang bro, I was half expecting you to show the part where you made your own copper mine to mine for copper on the home made PCB. 😂

Guy,you're really amazing. You just made my career grow one step further. Keep it up. Please let me know what to do in the case of a 10000w/48v??? Any changes to the circuit?

Awesome video! Best that the video that great scott did. My country is 120v not 220v how con make it 120v or 110v and any soon tutorial about making transformer?
@ele4853 Рік тому
Nice job! You mentioned on your written instruction on instructables web site that we can change the transformer and we could have 110VAC output and higher power. Is it possible to make one to output 4000W?

I started on red stone tutorials for MC and here I am now….it’s been a long night.
@dimmer4955 2 роки тому
Amazing. I will to construct this. But if the load is more then 1 kW power? have you idea for 1,5 kW or 3 kW power from 24v source?

I like this channel already. Well done!

Excellent video!!! Keep up, one question, how many irf MOSFET can I set up by channel?? Your design only contemplate 6 MOSFETs by channel. Regards.

good job sir! may I know where did you bought your pocket oscilloscope and hm? thanks
@fly3209 Рік тому
that transformer you connect to the output will filter very well any distortions or harmonics....

Can you make an example of a motor controller for us and how we'll use the concept to make a high power motor controller(for E-motorcycle)

Can I get more than 1000 watts from this same board? How to set overload protection, low battery protection and high battery protection?
@Dc_tech386 Рік тому
Great video but questions the gate diodes what type or they ziner or fast switching diodes
@vazenimudrost449 2 роки тому
Nice full bridge topology, have you modified sinewave with ferrite core transformer project?
@bakonyi72 Рік тому
Excellent project. I would like to ask if you haven't done UPS yet? I would be very interested.
