摘要

电动汽车(EV)和插电式混合动力汽车(PHEV)的电池通过电池充电器参与微电网或智能电网的潮流调节。本文提出了一种4S-V, lkW隔离式双向电池充电器。所提出的电池充电器电路工作在孤岛模式，包括两阶段转换，即交流-直流和直流-直流转换。双向交直流转换采用中性点箝位变换器，直流转换采用高频支路+高频中心抽头变压器+半桥接。所提出的电池充电器可以将三相公用电源转换为提供48V和20.83A的车载电池充电。同样，在微网孤岛模式下，当负载有电力需求时，同一个电池充电器可以将连接的电池放电回负载。

Design and Analysis of Efficient Battery Charging/ Discharging for V2G and G2V Application

Batteries of Electric Vehicles (EV) and Plug-in Hybrid Electric Vehicles (PHEV) participate in the regulation of power flow in microgrid or smart grid through battery charger. A 4S-V, lkW isolated bidirectional battery charger is proposed in this paper. The proposed battery charger circuit worked in islanded mode, comprises of two-stage conversion i.e., AC-DC and DC-DC conversion. Neutral-point clamped converter is used for bidirectional AC-DC conversion while for DC-DC conversion High-frequency leg along with high- frequency Centered Tap Transformer followed by Half bridge is used. The proposed battery charger can convert three phase utility power to charge the vehicle batteries by providing 48V and 20.83A. Similarly, the same battery charger can discharge back the connected battery to load when there is power demand of load in islanded mode of microgrid.
