三相全波桥式整流电路 three-phase full-wave bridge rectifier circuit
该系统以可控硅三相桥式全控整流电路构成系统的主电路，采用同步信号为锯齿波的触发电路。
The thyristor triphase-bridge full controllable rectification circuit is taken as main circuit of the system and the trigger circuit with saw-tooth synchronism signal is adopted.
它由三相或单相交流电压经降压和全波整流(或桥式整流)得到，无稳压及平波要求功率要足够大。
It consists of three-phase or single-phase AC voltage by the step-down and full-wave rectifier (or rectifier bridge) has been, no regulator and ping-wave large enough to require power.
