In order to improve the power generation efficiency of permanent magnet synchronous motor,a bi-directional DC/DC converter hybrid energy storage scheme of permanent magnet synchronous motor was designed,and the performance simulation analysis was carried out.The bi-directional DC/DC converter is used to connect the energy storage component and the load bus,and the control performance of the converter has obvious influence on the overall dynamic/static performance of the system.The re-sults show that the high voltage side current of the bidirectional DC/DC converter increases gradually and the highest output power is continuously rising.The bi-directional DC/DC converter and Buck circuit reach reasonable parameters,and can meet the stability and speed control standards required by the hybrid energy storage system.The parameters of the main circuit and Boost circuit of the bi-directional DC/DC converter designed in this paper are in a better state,which can achieve the goal of stable and efficient control of the hybrid energy storage system.The inductance and capacitance values meet the operating require-ments of the system,which can realize the fast response of the bidirectional DC/DC converter,can quickly control the current value,and obtain stable voltage parameters,and can meet the excellent dynamic control performance.
