一、原理利用电流负反馈改变可控硅整流器的移相角而获得陡降外特性(静特性)。通过改变移相触发电路的直流比较电压的给定值来调节输出电流。采用较大的输出电抗器和电压微分正反馈来改善动特性。
First, the principle of the use of negative feedback current to change the SCR phase-shift and get steep drop outside the characteristics (static characteristics). Adjust the output current by changing the reference value of the DC-phase comparison voltage of the phase-shift trigger circuit. Using larger output reactors and voltage differential positive feedback to improve dynamic characteristics.
