提高高压直流发生器稳定度的原理及措施

Principle and Measures for Improving the Stability of High Voltage DC Generator

在高压直流发生器中,通过调节主触发电路输出脉冲的触发角可调节半可控桥整流电路电压;亦可调节逆变触发电路使可控硅逆变电路的输出波形的脉宽或波形的频率发生变化,控制发生器的输出电压。在相位控制方式中,采用从高压侧引入采样信号方式,发生器稳定度更高一些。

In a high-voltage DC generator, the output voltage can be controlled by controlling the fire-angle of the output pulses of main trigger circuitry for hybrid rectifier, or by controlling inverter trigger circuit to change the wave form or frequency of thyristor inverter output. In the phase control mode, the generater can have even higher stability when the sampling signal is taken from the high voltage side.
