[Abstract]:Global environmental pollution and energy crisis are increasingly prominent, mainly because of fuel vehicles. As a new energy-saving and emission-reducing vehicle, electric vehicles play a substantial role in alleviating the two major world problems. At home and abroad, including institutions of higher learning, research institutions and large group enterprises, many organizations have invested huge financial resources to join the research and development team in this field. As a key technology in the development of electric vehicle, electric vehicle charging system has a great prospect. This paper first introduces the background and development prospect of electric vehicle, and then introduces the importance of the research of electric vehicle charging technology, and expounds the current situation and future prospect of electric vehicle charging technology. The basic structure of the charging system is introduced, and the bridge free boost PFC circuit, full-bridge ZVS inverter circuit and IGBT buffer circuit are analyzed. Secondly, the prototype of the charging system includes hardware implementation and software implementation. Hardware realization is mainly about the design of power loop and control loop. After the device parameters of the power loop are designed, the Simulink module in Matlab is used to model and simulate it. The control circuit mainly designs the power supply, IGBT driving circuit and the corresponding logic protection circuit of the control system. The realization of the software is based on DSP chip. Firstly, the PWM wave subprogram design and pid control subprogram design are carried out, and then the whole program is designed. Finally, after the prototype design of the charging system is completed, the performance of the charging system is tested with the designed experimental scheme. The test results basically meet the performance index, which reflects the feasibility of the subject design.
