【Abstract】 The paper mainly describes a charger based on single chip microcomputer STM32F103ZET6, which uses digital PI control technology to carry out single closed-loop control strategies. In this method, constant voltage charging and constant current charging becomes true. This paper shows every important parts, which contains the main circuit, control circuit, drive circuit, and control method. In the end of this paper, the results show that this design can work in the normal range when this equipment works on constant voltage charging and constant current charging, So the theory is effective.更多还原
