    摘要:

    提出一种基于模块化多电平矩阵变换器(MMMC)的插电式混合电动汽车(PHEV)综合变换系统,该系统同时兼顾电机驱动和电池管理,不需额外的充电电路。针对该系统,研究了外接电源充电控制策略。通过建立系统小信号模型和分析各部分功率关系,提出了以MMMC桥臂电流直接控制为核心的多层次电池荷电状态(SOC)均衡充电控制策略,包含相间、桥臂间以及本桥臂各子模块电池SOC均衡充电控制。搭建了RTLAB硬件在环仿真实验平台,实验结果验证了所提出的控制策略的有效性和可行性。

    Abstract:

    Based on modular multilevel matrix converter(MMMC), this paper presents a plug-in hybrid electric vehicle(PHEV)integrated conversion system. The proposed system can realize both motor drive and battery power management without additional charging circuit. To control this system, the charging control strategy from external power supply is studied. By establishing the small-signal model and analyzing the power relationship between different parts, a balanced charging control strategy by adjusting the battery state of charge(SOC)of each phase, bridge arm and the sub-module is proposed, the core of which is the MMMC bridge arm current control strategy. The experiments are conducted on the RTLAB hardware-in-the-loop simulation experiment platform and the results verify the feasibility and effectiveness of the proposed control strategy.
