Hi,
I have a circuit with two 220Volt DC rails (+-220VDC) feeding into a
100kHz h-bridge to generate two 120VAC 60Hz rails (after LC filtering),
for 240VAC split phase power.
For controlling this I think the half bridges should be controlled
independently to generate each 120VAC rail. So that would be two
PWM controller IC's running in parallel I guess? I was thinking of
using two UC3842's for this, and feeding the voltage feedback pins
60Hz sinewave to generate the AC outputs. Is there a better way to do
this? The circuitry using two of these IC's seems pretty complex.
Here's the circuit:
