摘要
提出了一种新型的三端口DC/DC变换器电路拓扑。在全桥变换器的基础上,增加一个变压器副边,形成三端口全桥变换器。该拓扑不仅输入电压变化范围宽,输入输出变比大,安全性高,实现了升降压变换;并且采用了软开关技术,适用于大功率场合。分析了该变换器的工作状态和开关模态,并通过Saber仿真验证了理论分析的正确性。
A novel three-port DC/DC converter for wave power generation system is proposed. The topology is a three-port full-bridge converter generated based on the two-port full-bridge converter by increasing a transformer secondary winding. The converter not only meet the demand of wide input range voltage application and high security,but also realize the buck-boost transformation. Adopting the soft switching technology, the topology is suitable for highpower application. Finally, in this paper the work states and operational modes are analyzed, and the theoretical analysis is verified by saber simulation.
