ABSTRACT:
An improved force commutated cycloconverter is provided by selectively switching a DC chopper to different groups of main thyristors including a thyristor to be commutated in the controlled sequence of thyristor commutations. The DC chopper is self-commutating. The forced commutating circuit is applied to various configurations of cycloconverters.
