Abstract
The article describes the fundamental principle and the control strategy of the voltage source rectifier(VSR) based on space vector pulse width modulation(SVPWM) control.It achieves high power factor rectifier accord-ing to theory analysis.By using Matlab,the system is built and came to some conclusion.A method of three-phase PWM rectifier double loop control system based on DSP is proposed.The experimental results of VSR based on TMS320F2812 DSP controller chip show that the proposed control strategy is feasible,and it realizes unity power fac-tor rectifier function.
