START APPARATUS FOR THYRISTOR INVERTOR

摘要

A start apparatus for a thyristor invertor relates to conversion technique and may be used in creation of control devices which prevent inversion upset in the moment of converter start, in frequency start circuits of synchronous motors. The apparatus is connected to the said invertor via elements of a power circuit and control units and consists of RC-circuit, capacitor thereof is shunted by a normally closed contact. The apparatus provides simplifying thyristor invertor control circuits with work reliability control.
