变模态宽电压范围双向LC谐振变换器
Bidirectional LC Resonant Converter with Variable Mode for Wide Voltage Range
摘要
Abstract
A bidirectional isolated resonant converter with variable mode and wide voltage range was proposed.The proposed converter has the advantages of BOOST circuit and flyback current feed topology.By reusing the pre-storage and flyback energy feedback of the resonant inductor,it can improve the gain from the battery side to grid side and the power density of the converter,while also reducing the current circulation.The converter adopts fixed frequency pulse width modulation and has multiple working modes,which is suitable for wide range output.the working principle of the converter was first introduced and the output gain when the energy flows in different directions was analyzed.Finally,on the premise of meeting the charge and discharge of the battery in the home distributed energy storage system,the devices and control parameters were designed to verify the correctness of the theoretical analysis.关键词
