Some typical topologies and the corresponding characteristics of energy storage control converters used in power system are comprehensively analyzed.According to the application of supercapacitor in power system,bi-direc-tional DC/DC converter as voltage Boost and stable regulator is used to stabilize the widely fluctuating voltage of su-percapacitor bank with its state of charge.As a result,the capacity utilization of supercapacitor is improved.Two bi-directional DC/DC converters are series connected to make the split capacitor voltage of the inverter DC bus control-lable.Moreover,a voltage and current double-loop control loop with repeated control method is also adopted to pro-mote the ability of imbalance and nonlinear load ability of supercapacitor energy storage system.The experimental re-sult verifies the presented topology and control method of supercapacitor energy storage system.
