Abstract

Multisource-based electric vehicle (EV) on-board charging system needed different converters for each source. This structure can be replaced with an integrated multipurpose converter. The combination of two single-ended primary-inductor converters (SEPIC) results in an integrated converter with some mechanical switches. This single converter satisfying all vehicular modes of operations. In this paper, the electric vehicle can be charged with two sources. The integrated converter incorporated charging system provides utilization of grid and photovoltaic (PV) power for charging the battery. Working of this power electronic system can be divided into different modes of operations such as plug-in charging (PIN), PV-based charging, simultaneous charging with dual sources and motoring operation. This system is effective for charging a light electrical vehicle with a 48V lithium-ion (Li-ion) battery. The motoring operation is validated with a brushless DC (BLDC) motor load of 1 kW power. The simulation analysis of this power electronic system is obtained with MATLAB Simulink environment.

电动汽车用双输入隔离集成变换器

基于多源的电动汽车车载充电系统需要针对不同的充电源配置不同的变换器。这种结构可以用集成的多用途转换器代替。将两个单端初级电感变换器(SEPIC)组合在一起，形成一个带有一些机械开关的集成变换器。这种单一的转换器满足所有车辆的操作模式。在本文中，电动汽车可以用两个电源充电。该集成转换器集成充电系统利用电网和光伏(PV)电源为电池充电。该电力电子系统的工作方式可分为插拔式充电(PIN)、基于pv的充电、双源同时充电和电机运行等不同的工作方式。该系统适用于48V锂离子(Li-ion)电池的轻型电动汽车充电。电机运行是通过1千瓦功率的无刷直流(BLDC)电机负载进行验证的。在MATLAB Simulink环境下对该电力电子系统进行了仿真分析。
