| Abstract: | As the critical process in battery production, battery formation is related to the trait and quality of battery and directly affects its production cost. A low voltage, high current DC/DC buck-boost converter is designed in this paper for the formation equipment of large capacity lithium ion battery and the selection of circuit basic topological structure, the designs of feedback module and peripheral control circuits are mainly included. Besides, the design of PWM driving circuit, the selection and calculation of the pa- rameters of high-frequency transformer are introduced in detail. The practical prototype test indicates that the two-way DC/DC converter is of the merits of high stal）ility, high reliability, small size, light weight and its charge/discharge efficiency can be up to 75% and 74% respectively. |
