Abstract

PURPOSE:To obtain simple construction which does not need a series current limiting resistor for an arc-suppression circuit by a method wherein a circuit formed by connecting commutation capacitors and two direction commutation thyristors in series is connected to the corresponding thyristors of a hybrid bridge rectifying circuit. CONSTITUTION:Power fed from the primary winding of a transformer Tr is supplied to load A1, A2, FW1, FW2 such as a motor through a hybrid bridge circuit formed by diodes D1, D2 and rectifying thyristors Q1, Q2 from the terminals u, v of secondary winding. A circuit formed by connecting two direction commutation thyristors Q31, Q32 and commutation capacitors C11, C12 in series is connected to each rectifying thyristor Q1, Q2.
