浅析用二极管抑制电磁继电器线圈瞬态电压的几种电路

Analysis of Several Circuits for Suppressing of Transient Voltage of Electromagnetic Relays by Diode

电磁继电器线圈在去激励过程中会产生的瞬态电压,若不对其进行有效抑制,会对电磁继电器输入电路造成损伤或损坏。全文对电磁继电器瞬态电压产生的机理、抑制瞬态电压常用的二极管及几种二极管抑制电路进行了介绍、分析、仿真和试验验证,阐述了每个电路的优缺点。

The transient voltage is often not suppressed, the circuit will be damaged. scribes advantages and disadvantages of each produced during the electromagnetic relay de -excitation process. If This paper analyses several circuits for electromagnetic relay, and de- circuits, and simulates and verifies the circuits.
