摘要

提出了一种适用于电动或插电式混合动力汽车的22kw车载充电器。为了实现高数量的器件,选择了完全模块化的电路和控制结构。电路布置由三个相同的相位单元(7.4 kW)组成,它们由两个相同的(3.7 kW)基单元组成。拟议的充电器已实施,其体积为11.1升,重量为12公斤。实验结果表明,在230 Vac的输入电压下,整个电池电压范围内的效率超过94%。满载和最佳效率的输出电压在315-395 V之间变化。

A 22 kW on-board charger for automotive applications based on a modular design
In this paper a 22 kW on-board charger for electric or plug-in hybrid vehicles is proposed. To achieve high quantities of devices, a fully modular circuit and control structure is chosen. The circuit arrangement consists of three identical phase units (7.4 kW), which are comprised of two identical (3.7 kW) base units. The proposed charger is implemented and has a volume of 11.1 liters and a weight of 12 kg. The experimental result indicates an efficiency of more than 94 percent over the full battery voltage range at an input voltage of 230 Vac. The output voltage for full load and best efficiency varies from 315-395 V.
