摘要
光耦反馈电路的特点是利用光耦合器实现信号传输与电气隔离,并与稳压管或可调式精密并联稳压器一同构成开关电源的反馈电路。
The characteristics of the feedback circuit based on optical couplers are using the optical coupler to realize the signal transmission and electrical isolation. It can be used to compose the feedback circuit of the switching power supply with the regulator tube or adjustable accurate shunt regulator.
