Broadband Equivalent Modeling and Common-Mode Voltage Conduction Analysis of Electrochemical Energy Storage System

Electrochemical energy storage system play an important role in the reform of national and construction Internet. Whether small or large capacity battery converters, characteristics their power electronics can generate high frequency common mode voltage that be potentially harmful to system. This paper systematically investigates common-mode interference (CMI) electrochemical The mechanism is revealed, a broadband equivalent circuit model established, effect parasitic capacitance on simulated analyzed, verified based laboratory data.
