Abstract
SummaryThis 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%.
