I need design variac electronic by specification
1. Input 220V AC
2. output can adjust voltage 0 - 220Vac, current maximum about 10 Amp
3. frequency output can adjust about 5 - 500Hz
from picture below can i design it? if can not do it, how the other idea for this?
and I use dspic controller code is sine wave table to pwm control H-bridge if i not use buck converter but i program level Voltage by software can i do it?
