基于比较电路原理实现的三相桥式整流器的触发线路

Trigger circuit of three-phase bridge rectifier realization based on comparison circuit principle

该晶闸管触发器采用集成运数放大器,移相触发脉冲的形成是根据三相交流电的各相与移相控制电压直接比较原理实现的。触发器具有优良的适应性、稳定性和控制品质,可直接应用于实际工程电路,且成本很低。

The shift trigger pulse of the thyristor trigger circuit with integration amplifier is generated by comparing directly principle of three-phase AC and shift-phase control voltage. The trigger circuit has comparative adaplabilily, stability and control character and cost effficiency,which can be used directly for engineering circuits.
