Abstract

一种小电容量补偿网络电路，第一开关模块(201)和第二开关模块(202)交替在关断状态和闭合状态之间进行切换，使得电容C1对补偿电容C3进行充电；以及第三开关模块(203)和第四开关模块(204)交替在关断状态和闭合状态之间进行切换，使得补偿电容C3放电，以对电容C2进行充电；通过控制第一开关模块(201)、第二开关模块(202)、第三开关模块(203)以及第四开关模块(204)的交替导通，使得对电容C1和电容C2的偏差进行处理，并获取到误差信号。由此实现了补偿电容C3可设计得很小，便于集成电路的集成，省去了外部补偿电容和集成电路管脚，降低了系统成本，提高了可靠性，解决了现有的补偿网络技术存在着的电源控制电路成本高以及电源可靠性低的问题。
