中文摘要	针对现有混合电动汽车能量管理系统所存在的功率密度低、可靠性差等问题,提出了一种基于级联H桥和矩阵变换器结构的高功率密度变换器拓扑。电池储能单元和车载内燃机发电单元提供整车驱动所需要的电功率,二者分别通过级联H桥电路和矩阵变换器与中频多绕组变压器输入侧绕组相连,中频多绕组变压器完成整车功率在电源和负载间的高效传输。其中,级联H桥电路作为储能单元控制电路的重要组成部分,在电池充放电过程中,负责均衡电池模块的动态电压。所提出的车载变换器降低了电池的串联规模和电容的使用量,显著提高了能量管理系统的功率密度和可靠性。在Matlab/Simulink环境中建立了相应的仿真模型,仿真结果验证了所提拓扑结构和相应控制策略的正确性。; A high power density converter topology based on cascaded H bridge and matrix converter is proposed in order to improve the performance of the conventional energy management systems with low power density and reliability. Energy storage system and on board internal combustion engine generator system provided the power demanded by the electrical motor,which connected to the primary windings of the medium frequency multi-winding transformer by the cascaded H bridge and matrix converter respectively. The medium frequency multi-winding transformer was used to achieve high performance power transfer between sources and load. As an important part of the energy storage control unit,the cascaded H bridge balanced the voltages of the battery packs. Using the proposed topology,the hybrid electrical rehicle( HEV) systems reduce the amount of batteries in series and capacitors,enhance the power density, and improve the reliability. The results of the simulation cases created in the Matlab / Simulink validate the correction of the proposed converter topology and the relative modulation strategies.
