Abstract

This paper reports on the AC-DC conversion process of fast-charging stations for electric vehicles (EVs). The suggested architecture of the converter is focused on the AC-DC converter of the H-bridge rectifier and then boosts the DC voltage. This boosts the reliability of the converter since only a fraction of the power travels into the converter, thus improving its efficiency and then use a push-pull converter for the conversion of DC to AC and stepping it down by flyback transformer and then rectified the AC voltage to get the pure required DC. For charging of an EV battery, demonstrations of the actions of the suggested conversions of voltage and PWM control of the MOSFET of the boost converter and push-pull converter by PIC16f690 microcontroller are described. The positive response of the suggested method is demonstrated by the results. It is checked that only a fraction of the power factor of about 96% is processed by the proposed converter for the overall power output spectrum.

集成PFC的推挽转换器电动汽车电池充电器

本文研究了电动汽车快速充电站的交直流转换过程。建议的变换器结构主要集中在h桥整流器的交直流变换器上，然后提高直流电压。这提高了转换器的可靠性，因为只有一小部分功率进入转换器，从而提高了其效率，然后使用推挽转换器将直流转换为交流，并通过反激变压器将其降压，然后整流交流电压以获得所需的纯直流。对于电动汽车电池的充电，描述了通过PIC16f690微控制器对升压转换器和推挽转换器的MOSFET进行电压转换和PWM控制的建议动作。结果表明，该方法具有良好的响应效果。结果表明，所提出的变换器对整个功率输出频谱的处理仅占功率因数96%左右的一小部分。
