Basically a VFD consists of 3 main components
1)six-pulse rectifier that converts three phase AC voltage
to DC voltage
2)capacitior bank for energy storage which stabilizes the
intermediate circuit DC voltage.
3)six-pulse IGBT inverter that converts the DC voltage to
AC voltage and vice versa.
The motor operation is controlled by changing the firing
angle(switching) of the IGBTs
