What is single phase semi-converter drive?

Single phase semi-converter drives are limited to the applications at 15 kW power level. The converter in the field circuit is a semi-converter. The armature circuit consists of two thyristors and two diodes connected in a bridge structure.

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 bride structure, and no diodes are present.
