Re: Buck converter with SG3524 and IR2117, problem with duty
What was the problem and how did you resolve it? (I am also having problems with giving varying duty-cycle PWM to this driver IC.)
@ FvM: Thank you very much for the guidance so far. But a simple 50/60Hz Transformer gave nothing but noise and distortion when I applied my accelerating-decelerating PWM waveform to it. And since then, my H-bridge isnt working fine. So are you SURE a simple 50/60Hz transformer can be used to...
Thanks a lot for your answers.
Actually we are making the inverter for 500W, 220Vac at the output. That means we cannot do filtering before the transformer because the current would be too much.
Secondly, if we use DC-DC conversion prior to the inverter H-bridge, what kind of converter would...
Question regarding TRANSFORMER:
Everyone suggests a Ferrite Core High Frequency Transformer for PWM-based Sine-Wave Inverters, but I am confused because I read somewhere that these transformers operate best at their resonant frequency (which is very high, above 20KHz) so they cannot be used to...
