提高继电器开关转换速度的电路

The Circuit for Speeding up the Changing Speed of the Relay Switch

在电子电路中，经常使用继电器来控制信号的工作状态，继电器从接通到断开会产生反峰电压，本文提出并分析了几个消除或箝制反峰电压并能提高继电器开关转换速度的电路，以供参考。

In the electron circuit,the electromagnetic relay is often used to control the working of signal.The peak inverse voltage will be produced from the relay's switching-on to its switching-off.This article shows and analyses some circuits which can remove or restrain the peak inverse voltage and speed up the relay switch's changing speed.
