路の制御装置。In an inverse conversion circuit formed by thyristors, the firing pattern of one thyristor on the same arm is on for up to 6 degrees from the rising edge of the half cycle, and 12 times from 6 degrees to 18 degrees.
Degree is off, 12 degrees from 18 degrees to 30 degrees is on, 30 degrees
The thyristor is controlled so that it is off for 6 degrees from 36 degrees and on from 36 degrees until the fall, and the half-cycle on/off of the other thyristor is controlled in a firing pattern that is opposite to that of the above thyristor. A control device for an inverse conversion circuit, comprising a control circuit.
