Answer Posted / sandeep vazhoor
Typical power circuit configuration involves 3 phase diode
rectifier at the input to convert the AC input to DC
voltage, LC or C filter to reduce the ripple in the DC
voltage. 3 phase IGBT inverter stage converts this DC
voltage into variable voltage variable frequency output as
per the desired pattern.
