给出一种性能优异的宽脉冲触发电路,脉冲的产生、移相由单片微机控制,其传输、放大由光电耦合信号传输与放大电路实现,脉宽和触发电流大小可调,适合任何晶闸管变流电路.
A wide pulse triggering circuit with excellent performance is provided. The pulse generation and phase shifting are controlled by a single chip microcomputer. The transmission and amplification are realized by the photoelectric coupling signal transmission and amplification circuit. The pulse width and the trigger current are adjustable in size and suitable for any thyristor Converter circuit.
