transformerless inverter
Hi everyone, I am planning to build an Inverter with a step up DC-DC stage switching at 20KHz coupled to the Inverter stage directly without an High frequency transformer. After the Inverter stage I intended to filter the resulting mid voltage range PWM output and use a 60 HZ power transformer to step up the ouput to 230v(note the inverter stage will be switching at 60HZ).
My question is that is such an inverter design possible? and if it is possible, what are the drawbacks/limitation. Any comment will be greatly appreciated.
Regards
Babs
