Abstract：Generation mechanism of EMI in high-power explosion-proof inverter was analyzed,and design method of an EMI filter for high-power explosion-proof inverter was proposed.The EMI filter uses "P" matching network structure based on a single LC filter,and realizes impedance matching of the explosion-proof inverter in the case of impedance mismatching,so as to improve EMI filtering effect.A 1 MW/1 140 V explosion-proof inverter was tested to verify validity of the EMI filter.
Keywords：explosion-proof inverterEMI filter"P" matching networkimpedance matching
