Nicely done. As digital board designers we tend to think of a trace as a line from point to point. (5mil here) However if you look at analog boards, and especially audio, those PCB designers seem to take the opposite approach and create isolated islands, leaving as much copper as is possible. So they simply create design rules mandating clearance and "flood" the plane as much as possible. This of course gives you more current capacity. The boards conduct heat better and will etch faster. Surface Mount technology originated in Audio/Visual markets where single sided boards were dominant An all SMT board needs no drilling or vias. Just mentioning this because there are many ways to do something right and its a fun exercise to consider the options.

I think a great addition to the project is the ability to select voltage and frequency. It would really be useful when testing equipment from foreign countries, like testing 120v/60Hz appliances in 230v/50Hz countries.
@VictorC173 Рік тому
For 120v the output DC voltage shout be half, or around 170-200v, and to change to 60Hz, you only need to make a jumper on the control board, there are a lot of information about (the board is egs002), you also need to change the voltage divide om the output so the board doesn't think it is under voltage or something like that...
@ELECTRONOOBS Рік тому
Yes, the driver, on the back it has a few pads. Bu shorting JP1 you change the frequency to 60Hz. Check here: 2.bp.blogspot.com/-dCnZ-R7fvxg/VxjjoYuf0TI/AAAAAAAAAYQ/beKxILumNvIr-FTpv1uquqtYu6-A6aWiwCLcB/s640/jumper%2Bsetting.jpg

@boneikribo420 Рік тому
the diode you are using is not recommended for high frequency, try to use a high frequency diode like mur460 or her408, if you use a bridge diode as in the video it will usually heat up quickly and break easily and is recommended for low frequency. and if the circuit works at 20watt even without load try to add a 20k potentiometer on pin 6 ic sg3525, then try to connect it to the power supply, then rotate the potentiometer until you get the lowest standby amperage, usually the problem occurs in the mismatching of the transformer and pwm frequency, pin6 on the sg3525 ic to adjust the frequency, and it could also be a problem with the high voltage 300v output diode, try using an ultrafast diode.

Yes, these are kinda nice but watch the bootstrap voltage on the gate drivers. I blown many ir2110 and mosfets before I scoped the gate drivers power rails. My inverters were randomly blowing when idle or at power-off. I was deep in the dead-time settings but missed the fact that the gate drivers were ringing like mad and spiking to 18v regularly. Lowering the esr on the bootstrap cap did the best in lowering the ringing amplitude. Zenners are the last frontier. My measurements shown 30-40ns long spikes...

A trick that will not need a redesign is to mount the IGBT's and other fets under the board so that you can mount to a Heatsink like an amp or some of the grid tie inverters this will allow more room for heat sink thus better cooling as those caps behind the IGBT's are in the way, but other then that very clean board.
@shadmtmtn1603 Рік тому
And the caps themselves are too close to the transformer, they won't last long with that heat, maybe they should be on the other side too !

Andrei, Another fantastic project. This was very educational and interesting. I began to wonder what would be necessary to convert to 120 V output at 60 Hz since I live in the U.S. I saw the comments by Victor Silva and yourself below. So that pretty much answered that question (frequency sounds easy with voltage being a little harder). Thank you for creating this wonderful project and sharing it. It was very enjoyable to watch.
@ELECTRONOOBS Рік тому
Frequency is easy to change. For the voltage, you would need to supply the IGBT bridge with 220V instead of 380V. That's why the transformer has 2 outputs. But you will need to change the PCB so the 220V is connected to the IGBT instead of 380V. I haven't tested this yet so this is only a recomendation. Have that in mind!

@youneshamache3314 Рік тому
Nicely done ! I've made an inverter few months ago based on the same ship, the most challenging part to me was the inductor filter, I struggled alot to find the right material core (it has to be a low permeability core), adding to that I had to reach around 3.3mH inductance, but after 80 turns I almost had no window area left to add more turns and I only got 1.2mH, So I had to compensate that with a higher output capacitor ! It was so far my best project and the satisfaction you feel once you get your output sinewave is just priceless ! I would like to mention a last thing, do not trust the readings of the LCD display it's fake !

@@samcreation9225Well it's not really robust but you can improve it performance, usually what burns first is the ir2110s chips I recommand you replace it with 4xtlp250 mosfet drivers, it is also recommanded to isolate the control circuit from the power circuit GND, also make sure that your mosfets are of good quality and can withstand the voltage and current ratings of the circuit ! And finally use a proper heatsink (the bigger it is the better is) and a fan if the mosfets get hot alot !
