Power Control of Three-phase Boost-type PWM Rectifier Based on Passivity

This paper established the power Euler-Lagrange(EL) model of three-phase boost type PWM rectifier in synchronous dq coordinates based on its power circuit.According to the passivity of PWM rectifier,passivity power controller was designed by a new damping injection method.The passivity power controller transforms the power control system of PWM rectifier into decoupling one.The PWM rectifier using the passivity power controller has many advantages,such as fast response,good stability,and is better than one using other power control strategies.The rectifier has fast power response and constant DC voltage under load disturbance specially.The new design method of passivity power controller of PWM rectifier was proved feasible by simulation test.
