我首先想到的是，我能得到一个全波整流电路和信号转换为直流(交流等)。
My first thought is that I could get a full wave rectifier circuit and convert the signal (AC like) to DC.
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.
它包括一个全波整流电路和正弦信号源。
