Power Supplies for
Electric Vehicle Charging
电动车和电动出行将是急需减少碳排放世界的未来。为了让电池供电的汽车具成本效益，充电器必须越来越高效且经济。随着最新拓扑和半导体技术的发展，数千瓦的功率转换水平不断进步，因此交流/直流辅助电源在效率和价值方面也必须符合充电器的要求。充电电箱和充电站通常安装在过压类别III (OVC III) 的环境之中，由于可能会有雷击引起的电压骤降、电涌和瞬态，因此电源必须具备承受这些风险的能力。此外，温度也可能大幅变化，可用的交流电源电压为三相480VAC或277VAC。在这种环境下，辅助AC/DC模块必须与提供内部电压转换和隔离的开关稳压器和DC/DC转换器一起可靠地工作。

DC/DC Converters
Circuitry in battery charging applications often requires DC-DC converters to produce auxiliary rails and isolated power for communication interfaces. High-efficiency board-mounted products such as the 4:1 input 40W RP40 series and the 20W REC20 series feature six-sided shielding in 2”x1” packages, which are ideal for providing control circuitry power in charging stations and battery management systems. For lower power battery management applications, there is the 4:1 input 8-watt RP08 series, which includes parts with an input range of 160V and is suitable for strings of batteries. When a low-power 5V isolated rail is required, perhaps to provide a -5V supply for analog circuitry or for an isolated interface in a smart EV charger, the RFMM-0505 or RKE series converters are suitable; they feature 1W output, 4kV isolation, and comprehensive safety certifications.

Switching regulators
Non-isolated switching regulators provide high-efficiency replacements for linear regulators in battery charging systems. The R-78E-1.0 series, for instance, peaks at 97% efficiency, with 1-amp output current from 3.3V, 5V, or 12V outputs and input ranges up to 28V. For output power up to 3kW, the half-brick RBBA3000-50 product is a buck-boost converter, which has an input range of 9–60V and an output of 0–60V that can be preset; this can be above or below the input voltage. Its typical applications include 48V to 24V or 12V to 24V battery power conversion in electric vehicles and battery voltage stabilizers in charging stations for UAVs and drones.
