摘要
This article aims to propose a new nonisolated step-up multiport dc-dc converter. The proposed topology is a dual-input dual-output dc-dc converter with different output voltages levels. This makes it possible to be used in hybrid energy systems with different input sources as well as in electric vehicles to supply the traction motor and auxiliary loads. The proposed converter is capable of providing high voltage gains with small values of duty cycles and low normalized peak voltage stress across the semiconductor devices. Therefore, the switches with small turn-on resistance and the diodes with a reduced nominal voltage can be used, which in turn reduces the switching and conduction losses. The operation principles of the proposed converter are explained and steady-state analysis is carried out. Then, the circuit performance is compared with other related step-up multiport dc-dc converters in the literature. Eventually, the performance of the proposed converter is validated with experimental results.
