由施密特触发器构成的三相移相触发器的设计

Design of three-phase and movable phase trigger based on Schmitt trigger

提出了由施密特触发器构成三相移相触发器的设计思路及方法,即在给定电压控制下,输出脉冲能在0～150°夹角范围内移相,其主要应用于调节全控整流桥电路的输出功率.

The thinking and methods of designing a three-phase and movable phase trigger based on Schmitt trigger are presented. The phase-shift of output pulse ranges from 0° to 150°.The design is used mostly to modulate power （DC voltage adjustment）in three-phase bridge circuit of silicon controller（SCR）.
