Design of High Current Two-Way DC/DC Converter in Lithium-Ion Battery Formation Equipment

Abstract:

As the critical process in battery production, formation is related to the quality of battery and directly affects production cost. A low voltage, high current DC/DC converter is designed for large capacity lithium battery formation equipment. Design of basic topological structure, feedback module and peripheral steering circuit are introduced. Besides, design of PWM driving circuit and parameters of high- frequency transformer are presented in detail. This two-way DC/DC converter has features of high stability, high reliability, small size, light weight and its efficiency of buck-boost can be up to 84% and 83% respectively.
