摘要

双向dc/dc变换器的选择在电动汽车电池充电器中起着至关重要的作用，本文提出了一种无缓冲电路的双向电池充放电拓扑结构。在升压和降压模式下进行不同频率的操作，以实现两个方向上的零电压切换。电池侧变换器选用电流馈电半桥升压变换器，实现变压器一次到二次的2倍电压增益。利用MATLAB/Simulink对1KW电池连接系统进行了从满载到空载的软切换损耗的识别和校正。

An Efficient Bi-directional DC/DC Charger for Electric Vehicle Battery Charging

The choice of bi-directional dc/dc converter plays a vital role in the battery chargers of electrical vehicles (EVs), In this paper, a bidirectional battery charging and discharging topology without snubber circuitry is proposed. A different frequency operation is performed in step-up and step-down mode to achieve zero voltage switching in both the directions. The battery side converter is selected as a current-fed half bridge boost converter to achieve 2X voltage gain from primary to secondary of transformer. losses of soft switching from full load to no load and vice-versa are identified and rectified by using MATLAB/Simulink for 1KW battery connected system.
