Abstract

This article presents a simple integrated onboard charger (OBC) for electric vehicles (EVs) with a two-motor propulsion system, especially used in all-wheel drive (AWD). In order to ensure seamless integration of the charging system, the proposed charger does not use any additional components but reuses the two three-phase inverters that drive the two distinct permanent magnet synchronous motors (PMSMs) to charge the EV battery. The first inverter is reconfigured into an active rectifier that ensures a unity power factor is drawn from the grid, and a stable DC-link voltage is obtained. The second inverter is reconfigured into a DC–DC converter to control the output voltage and current for charging the battery. There are no additional elements present; hence, this innovation not only reduces the cost of EVs but also reduces the overall weight. The charger utilizes the motor windings as grid harmonic filters that ensure a total harmonic distortion (THD) below 5%. A simple proportional–integral (PI) and proportional–resonant (PR) control is implemented to achieve these objectives. Furthermore, the motors do not generate torque while charging, making it a suitable solution for AWD EVs. Simulation and experimental results are provided for a 1-kW prototype to evaluate the performance of the proposed charger using a 110-Vrms, 60-Hz supply with an output voltage of 48 V.

用于插电式双电机电动汽车的单相集成车载充电器

本文介绍了一种简单的集成车载充电器（OBC），用于双电机推进系统的电动汽车（ev），特别是用于全轮驱动（AWD）。为了确保充电系统的无缝集成，拟议的充电器不使用任何额外的组件，而是重复使用驱动两个不同的永磁同步电机（pmms）的两个三相逆变器来为电动汽车电池充电。第一个逆变器被重新配置为一个有源整流器，以确保从电网中获得统一的功率因数，并获得稳定的直流链路电压。第二个逆变器被重新配置为DC-DC转换器，以控制为电池充电的输出电压和电流。没有额外的元素存在；因此，这一创新不仅降低了电动汽车的成本，而且降低了整体重量。充电器利用电机绕组作为电网谐波滤波器，确保总谐波失真（THD）低于5%。为了实现这些目标，采用了简单的比例积分（PI）和比例谐振（PR）控制。此外，电动机在充电时不会产生扭矩，因此适合全驱电动汽车。仿真和实验结果提供了一个1千瓦的原型，以评估所提出的充电器的性能，使用110-Vrms， 60 hz电源，输出电压为48 V。
