This paper presents a high gain modified three‐port dual boost single‐ended primary‐inductor converter (SEPIC) converter operated hybrid photovoltaic (PV)/battery electric vehicle to improve the power transfer capability and efficiency of the power conversion stage. The proposed three‐port dual boost high gain SEPIC converter accepts wide voltage range of input then the conventional single stage SEPIC converter. The three‐winding high frequency coupling transformer integrates the two input sources and step‐up the input voltage. The theoretical and experimental analyses are presented to validate the performance of the proposed modified SEPIC converter in boosting the wide range of input voltage. A 6 kW, 12 to 600 V of experimental model has been developed and tested. The efficiency obtained from the designed model is around 94.11%.

基于PV的SEPIC变流器混合动力电动汽车（PV-HEV）的实验研究

本文提出了一种高增益改进型三端口双升压单端一次电感转换器（SEPIC）转换器操作的混合光伏（PV）/电池电动汽车，以提高功率传输能力和功率转换级的效率。与传统的单级SEPIC转换器相比，拟议的三端口双升压高增益SEPIC转换器可接受较宽的输入电压范围。三绕组高频耦合变压器集成了两个输入源，并提高了输入电压。进行了理论和实验分析，以验证所提出的改进型SEPIC转换器在提升宽输入电压范围内的性能。已经开发并测试了6 kW，12至600 V的实验模型。从设计模型获得的效率约为94.11％。
