title = "Study on electromagnetic emission of DC SSR with transformer isolation",
abstract = "In this paper, the electromagnetic emission of a DC SSR (Solid State Relay) in which transformer isolation circuit was adopted was investigated at working frequency and higher harmonic. The equivalent circuit of dual-winding transformer of iron-core was proposed considering leakage inductance, iron loss in core and cupreous loss in winding. The EMC model of the DC SSR was built by Orcad Pspice and Ansoft QSD to predict electromagnetic radiation at the frequency from 10kHz to 18GHz which was prescribed in GJB 152A-RE102. The results of both simulation and experiment showed that the electromagnetic emission exceeded the limit of RE102. The electromagnetic emission of the DC SSR was divided into two parts: one generated by the inside circuit and another generated by external cables. And it was concluded that the electromagnetic emission was mainly generated by external cables. In order to improve EMC of SSR, an EMI filter was proposed to reduce the current in external cables so as to suppress the electromagnetic emission. The results showed this method was useful.",
