摘要：

双向功率变换器是实现电动汽车V2G(Vehicle to grid)技术的关键性设备。引入集成技术,利用共享车载驱动电机和驱动电力电子变换装置,提出一种新的集成式双向车载功率变换器。它既可以将电动汽车蓄电池能量回馈给电网,又可完成蓄电池充电功能。集成式功率变换器具有单相、三相充/放电接口,实现了一机多口,增强了车载系统的紧凑性。分析不同充/放电模式下的集成功率变换器拓扑,给出了充/放电模式下的控制策略。最后,给出了仿真和试验结果,验证了多端口集成车载功率变换器的可行性。

关键词: V2G(Vehicle to grid)技术, 充/放电模式, 集成车载变换器

Abstract:

Bidirectional power converter is the key device to realize vehicle to grid(V2G) technique. Introducing integration technique, a new integrated onboard power converter is proposed by sharing the driving motor and the driving power electronic conversion device. It can feed the battery storage energy into the grid and charge the battery. The integrated converter has singe-phase charging and three-phase charging interface, realizes one charger with many ports, and enhances the compactness of the onboard system. The integrated converters under different charging modes are analyzed, and the control strategies under different charging and discharging modes are given. Finally, the simulation and experimental results are given to verify the feasibility of the multi-port integrated converter.

Key words: V2G(Vehicle to grid), charging/discharging mode, integrated onboard converter
