A New Type of Dual-Buck Single-inductance Inverter

在双Buck半桥逆变器的基础上给出一种新型双Buck单滤波电感逆变器,在保留双Buck逆变器无桥臂直通风险、换流时间短等优点的情况下,通过新增控制桥臂,实现单电源供电以及单电感滤波,减小了逆变器的体积和损耗,增加了系统功率密度。详细分析了所给逆变器的工作原理,介绍了滤波电感的设计过程,并制作了一台1 200 W的原理样机,通过仿真及实验验证了所提逆变器拓扑的有效性。

Based on the dual-Buck half-bridge inverter,a new type of dual-Buck single-filter inductance inverter is given,while retaining the advantages of the dual-Buck inverter without the risk of bridge arms and short commutation time,by the new increase of the control bridge arm,single power supply and single-inductance filtering are realized,the volume and loss of the inverter are reduced,and the power density of the system is increased.The working principle of the given inverter is analyzed in detail,the design process of the filter inductance is introduced,and a 1 200 W principle prototype is made,and the effectiveness of the given inverter topology is verified through simulation and experiment.
