摘　　要：介绍了相关标准中对浪涌电压抑制的要求,并总结比较了几种常用的浪涌电压抑制电路。在此基础上,设计并研究了一种新颖的基于集成芯片的两级级联拓扑结构,克服了传统单级浪涌抑制方案中功率器件电流不均衡的难题。该电路可以同时驱动控制两级浪涌电压抑制电路,响应速度快,自动调整性更好,体积更小,可靠性更高。最后通过仿真和试验验证了该电路的可行性。The requirements of surge suppression in relevant standards are introduced,and several common surge suppression circuits are compared.On this basis,a novel two-stage cascaded topology based on integrated chip is proposed and analyzed,which solves the current imbalance problem of power devices in traditional single-stage surge suppression schemes.This circuit can drive and control two-stage cascaded surge suppression circuits at the same time,with fast response,better automatic adjustment,smaller volume and higher reliability.Finally,the feasibility of the circuit is verified by software Simulation and experiment.
