Study on EMS of solid state relay (SSR) with voltage dips and short interruptions

In this paper, the electromagnetic compatibility susceptivity (EMS) of a DC SSR with interference of voltage dips and short interruptions was investigated. The high frequency model of SSR considering model parameters of BJT (bipolar junction transistor) and parasitic parameters of wires on PCB was proposed to obtain the equivalent circuit and then predict EMS of SSR with voltage dips and short interruptions prescribed in GB/T 17626.29.
