一种磁保持继电器驱动电路的设计

Design of driver circuit for magnetic self-perpetuating relay

磁保持继电器是一种能耗低、稳定可靠的双稳态继电器,采用脉冲驱动。本文介绍了一种通用的驱动电路,中央控制单元输出的两路信号触发IR2110组成的驱动电路,驱动电路控制由MOSFET搭接的H桥主电路,实现磁保持继电器在两个稳态之间相互切换。总体结构简单、通用,工作可靠。

Self-perpetuating relay is a bistable relay which is low power consumption, stably working and is driven by impulse. In this paper, a common driver circuit is introduced, two signals from CPU trigger the driver circuit composed by chip IR2110 ,driver circuit controls the H-bridge main circuit assembled by MOSFET, so that the bistable state of self - perpetuating relay can converted stably. The driver circuit is simple-design, universal-used and reliable-working.
