Electrical Characteristics of High-Voltage High-Power Fast-Switching Reverse-Conducting Thyristor and Its Applications for Chopper Use

The structures, features, electrical characteristics, and successful application results of two types of high-voltage high-power reverse-conducting thyristors are described. The first has blocking voltage ratings of 1300 V and current ratings of 400 A in the forward direction and 150 A in the reverse direction, with a turn-off time of 30 ¿s. The second has ratings of blocking voltage of 2500 V, current ratings of 400 A in the forward direction and 150 A in the reverse direction, with a turn-off time of 40¿s.
