Abstract

一种保护电路，包括输入电源(1)、储能电容(C)、供电输出电路(2)、掉电检测电路(3)以及处理器(4)；输入电源(1)与储能电容(C)相连，储能电容(C)连接供电输出电路(2)，输入电源(1)用于对储能电容(C)充电并对供电输出电路(2)供电，储能电容(C)用于在输入电源(1)掉电后对供电输出电路(2)供电，供电输出电路(2)输出的电压分别输入至功率放大器(100)的基极和漏极；掉电检测电路(3)连接输入电源(1)，并在检测到输入电源(1)掉电后，将掉电信息发送至处理器(4)，由处理器(4)输出控制功率放大器(100)的基极输入电压小于或者等于零的信号至供电电路后，再输出控制功率放大器(100)的漏极输入电压为零的信号至供电输出电路(2)，以保护功率放大器(100)在掉电后不受损坏。
