This morning I changed HCPL3120 supply to 3 isolated 15V DC as you said, at a point i got a signal and I have upload it. Your feedback on that will be very helpful. Like you said I will put a load with filter and test one leg, however I am planning to integrate inverter with a DC-DC booster...
Thanks,
Got it about LC filter, I tested this circuit without load as I am having some issues with calculations. Picture DSC_0142 was taken at output with reference to ground while other picture across two output terminal. Problem is I don't know why I am having output just of 2V as I should be...
Hi,
I am building a Full-Bridge Inverter using four IGBT and four drivers for each IGBT. Driver is HCPL-3120, all four drivers are supplied with 15VDC isolated supply. I am switching using M bed micro controller LPC1768 generating two PWM signal working alternately, first signal turns IGBT 1...
