Hi,
We are doing a pure sine 110vac inverter.
Its +/-15% so vac can be up to 126VAC.
So max peak is 179V
As such, woudl you agree, we need our VDC input to be 200V?

so many questions, so little information

if the source can support it, why not boost whatever the input voltage is to
180V plus whatever overhead one needs to get the desired output?

what's the input voltage?
what's the required output power? available input power? etc etc etc

No, I would not agree.

Thanks, i mean the input to the actual inverter itself. The atual input is 18V. We will isolate this, then boost it up to 200v.
I guess it has to be 179V min....just if we pick 179v...then our sinusoidal PWM has to be able to go to 100%.
