一种高效率双输入双输出高升压DC-DC变换器

The proposed topology is a dual input dual output structure with different output voltages, which makes it suitable for use in hybrid energy systems as well as supplying the traction motor in electric vehicles. The proposed converter can provide high voltage gain with a low duty cycle compared to other multi-port converters. The lack of a transformer and coupled inductor makes the final volume of the suggested converter and manufacturing costs lower. Also, the average voltage stress on power semiconductors of the suggested topology is low. Finally, experimental results of a 250 W laboratory prototype with 96.5% efficiency are used to validate the theoretical analysis.
