摘　　要：为了提高永磁同步电机的发电效率,设计一种永磁同步电机双向DC/DC变换器混合储能方案,并开展性能仿真分析。利用双向DC/DC变换器连接储能部件与负载母线,该变换器的控制性能对系统整体动/静态性能存在明显影响。研究结果表明:在Buck模式下仿真测试得到,双向DC/DC变换器高压侧电流逐渐升高,产生了持续上升的最高输出功率。双向DC/DC变换器与Buck电路达到了合理的参数,能够达到混合储能系统要求达到的稳定性与快速性控制标准。本设计的双向DC/DC变换器主电路与Boost电路各项参数处于较优的状态,能够实现对混合储能系统进行稳定高效控制的目标。电感与电容值满足系统运行要求,可以实现双向DC/DC变换器的快速响应,能够快速控制电流值,并获得稳定的电压参数,能够满足优异的动态调控性能。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.
