一种适用于宽输入电压范围的三端口变换器
A Novel Three-Port Converter for Wide-input-voltage-range Application
摘要
Abstract
An H-bridge three-port converter (HB-TPC) for wide-voltage range application was proposed. The HB-TPC is generated based on the H-bridge Buck/Boost converter by introducing a transformer and a secondary rectifier and filter circuit to build the third output port. The converter is composed of two bidirectional ports and an isolated output port. The three ports are connected to input source, battery and load respectively. Power management among the three ports is achieved with the proposed HB-TPC. The equivalent circuit of primary side is H-bridge Buck/Boost converter, which can meet the demand of wide-input-range-voltage application. The work states and operational modes of the proposed converter were analyzed in detail. Furthermore, the relationship between the switching sequences of the power switches and the DC-bias value of the transformer was analyzed and an optimized switching scheme was designed. Finally, the topology and analysis were verified by experimental results.关键词
