Starting Conditions for the Conversion of the Converter to the Compensating Mode of Operation

Abstract

The paper present the results of studying the process of forming the commutating voltage of a compensation converter, implemented to the three-phase combined bridge circuit, are presented. It is shown that the transition of the converter from the non-compensation mode of operation to the compensating one requires the research of three modes: 1) starting, in which the commutating voltage has an insignificant value, 2) transient mode characterized by increased values of the commutating voltage, and 3) compensating. The results of the study of the process of forming the commutating voltage in three situations of the starting mode are given because the volume of publication is limited. A conclusion is made about the optimal conditions for recharging the capacitors of the commutating link.
