摘要：AC/DC converters are facing an increasing strict requirement on the conversion efficiency and power density with the development of More-Electric-Aircraft (MEA). In this paper, cascaded H-bridge topology is chosen as a fascinated candidate for front-end rectification topology for its superior in reducing the current harmonic, power loss, and EMI interference. LLC resonant converters, known for its high efficiency at a wide load range, are adopted as the back-end of the two stage converter, with two modules in parallel. Corresponding control method is proposed to ensure the unity input power factor, stable output and power sharing between parallel modules. Two-stage two-unit AC/DC simulation model and experimental platform are established to verify the topology and control strategy proposed. © 2018 IEEE.
