研究了一种适用于车辆到电网（V2G）和分布式发电（DG）系统的无直流侧电解电容的隔离型三端口变换器（TPC）。采用基波分量近似法建立了变换器的小信号模型。此外，采用高带宽电流控制器对直流电源电流进行控制，可以降低直流侧的倍电网频率涟漪功率。为了消除电网LC滤波器的谐振，提出了一种dq同步坐标系下的并网电流控制器，该控制器具有虚拟阻尼补偿功能，可同时实现有功和无功调节。仿真结果验证了该控制策略的有效性，并给出了实验结果.
An isolated three-port converter (TPC) without DC-link electrolytic capacitor is studied in this paper, which is applicable to vehicle to grid (V2G) and distributed generation (DG) system. The small signal model of the converter is formulated by means of fundamental component approximation. Furthermore, a high bandwidth current controller is employed for DC power source current control which can reduce double grid frequency ripple power on the DC side. A grid-connected current controller in dq synchronous frame for both active and reactive power regulation with virtual damping compensation is presented to eliminate resonance of grid LC filter. Simulation results validate the control strategy, and experiment results will be provided in full paper.
