Abstract
The rapid development of power electronics technology is promoting the development of the converter, such as rectifiers, inverters, inverter and so on. The use of them is promoting the development of society in aspects of social life. However, harmonic pollution problems are growing, and more and more people are aware of the problem gradually. To solve this problem, PWM rectifier technology attracted the attention of many scientific and technical personnel. Three-phase voltage type PWM rectifier can achieve unity power factor operation, stable voltage output, good dynamic response, network testing and DC-side two-way flow of energy. Therefore, it has become social hot research topic in the field of power electronics.
This paper describes the background and current situation of PWM Rectifier, give the significance of this project, purpose and content. This paper analyzes the SVPWM (space vector pulse width modulation) technology. Firstly, this paper include the main circuit, DSP control circuit, protection circuit to complete the hardware design three-phase voltage type PWM rectifier, inductor DC side measured as net current design, the synchronization detection signal design, sensor design, and so on. Finally, this paper makes a systematic software design, which includes the main program flow chart, the interrupt service routine, the control algorithm procedures
