Abstract

1,162,000. Rectifying circuits. ALLMANNA SVENSKA ELEKTRISKA A.B. 23 Dec., 1966 [28 Dec., 1965], No. 57635/66. Heading H2F. A converter in which each rectifier comprises a number of thyristors in series is provided with a damping circuit connected across the rectifier chain which is so dimensioned that the ringing occurring, on switching off a thyrister, does not exceed its rated peak inverse voltage. Overvoltage protection means is also provided.
