Title Design of three-phase PWM Rectifier power
Abstract
With the serious problem of harmonics pollution to the power system and the need of high performance of AC drive application and the development of the green power technology,PWM rectifier has e a highlight in the field of power electronics. Three-phase PWM rectifiers have recently been an active research topic in power electronics due to more virtues, such as sinusoidal input currents, unity power factor , steady output voltage, good dynamics and bin-directional energy flow.
Firstly, the thesis elaborated the basic principle of work for the PWM rectifier according to main circuit topology of three-phase voltage-type PWM rectifier, and the establishment of a three-phase voltage-type PWM rectifier model; Secondly, the thesis proposed the three-phase voltage-type PWM rectifier’s control strategy. Based on the control strategy it has studied the space voltage vector pulse width modulation control method. With pany's TMS320LF2407A chip as controllers, choose pany IPM module for three-phase voltage source PWM rectifier system hardware design, including the main circuit, detection control circuit, protect circuit, etc.; Combined with the basis of hardware design, software design plete corresponding.
