摘要
结合GJB 151A-1997的电磁兼容相关要求,针对某机载270 V高压直流电路浪涌电流试验超标的案例,提出了EMI滤波器中增加浪涌抑制电路的方法,不影响EMI滤波器电磁兼容性能的同时,解决了浪涌电流抑制问题。
According to the electromagnetic compatibility requirements of GJB 151 A-1997, aiming at the failure case of surge current test of airborne 270 V high-voltage DC circuit, a method of adding surge suppression circuit in EMI filter is proposed, the problem of surge current is solved without affecting the electromagnetic compatibility of EMI filter.
