What is single phase full-converter drive?

A single phase full-converter drive is a two quadrant drive and is limited to applications up to 15 kW power level. The converter in the field circuit should be a full-wave converter to reverse the polarity of the field current. During regeneration for reversing the direction of power flow, the back emf of the motor is reversed by reversing the field excitation.

What is the difference between a semi-converter and a full-converter?

The main difference between a semi-converter and a full-converter is that the semi-converter always has equal number of diodes and thyristor connected in a bridge structure whereas a full-converter has all the thyristors connected in the bridge structure, and no diodes are present.
