摘　　要：电动汽车与电网端的能量传递过程得到广泛研究。鉴于此,提出了一种适用于电动汽车电池充电器的双向交错无桥变换器。该变换器通过单元整合,取消了桥式结构。详言之,该变换器前级可等效为双向交错无桥Boost电路,以满足电网和直流母线的交互;后级可等效为双向Buck-Boost电路,以满足直流母线和汽车电池的交互。对新型双向变换器的正向和反向工作过程进行分析,同时阐述新型变换器的功率控制和电流控制策略,推出相关的控制算法。最后,通过PISM软件对该变换器进行了仿真验证。结果表明,该变换器不但具有G2V和V2G两种工作模式,并拥有较高的功率因数。The energy transfer process between electric vehicle and power grid has been widely studied.In view of this,a bidirectional interleaved bridgeless converter suitable for electric vehicle battery charger is proposed.The converter eliminates the bridge structure through unit integration.In detail,the front stage of the converter can be equivalent to a bidirectional interleaved bridgeless boost circuit to meet the interaction between power grid and DC bus.The latter stage can be equivalent to a bidirectional buck boost circuit to meet the interaction between DC bus and automobile battery.The forward and reverse working processes of the new bidirectional converter are analyzed.At the same time,the power control and current control strategies of the new converter are described,and the relevant control algorithms are introduced.Finally,the converter is simulated and verified by using PISM software.The results show that the converter not only has two working modes of G2V and V2G,but also has high power factor.
