摘要

提出了一种宽输入输出电压范围的并联负载谐振变换器。该变换器能够在开关的零电压开关通通和二极管的零电流开关关断下工作，并能在宽输入输出电压范围内的窄开关频率下工作。通过调整变压器的匝比，可以合理选择谐振电容，使变换器更适合大功率应用。通过3kW样机的实验结果验证了所提出的概念。

New parallel loaded resonant converter with wide input and output voltage range

This paper proposes a new parallel loaded resonant converter with wide input and output voltage range. The proposed converter is capable of operating under zero-voltage switching (ZVS) turn-on of switches and zero-current switching (ZCS) turn-off of diodes and works in a narrow switching frequency under wide input and output voltage range. Also, proper selection of resonant capacitor is possible by adjusting the turn ratio of the transformer, making the proposed converter more realizable in high power application. Experimental results from a 3kW prototype are provided to validate the proposed concept.
