In order to reduce the charging/discharging current ripple,extend battery life,and increase the rate of power equalization of battery energy storage system( BESS) with multiple parallel converters,a power distribution control scheme based on the nth order of the state-of charge( SOC) for three-phase interleaved parallel DC/DC converter was presented. The voltage compensation coefficient was introduced to prevent the DC bus voltage drop in the battery discharging process. In the two-stage charging process,th...
