Abstract Aiming at that current control strategies of voltage source PWM rectifier under unbalanced voltage conditions at home and abroad exist complicated control structure and unsatisfactory control performances, hybrid passivity based control strategy by DC voltage loop(PI) and passivity based current controller is proposed in the paper. Based on EL model of the PWM rectifier, passivity based current controller is designed by damping injection method. According to passivity based current controller, switch function that can compensate unbalanced voltage conditions is obtained. All harmonics in input current of rectifier can be eliminated or restrained and DC output voltage of rectifier is kept constant by hybrid passivity based controller based on the real time value of voltage and current. Hybrid passivity based controller can make rectifier having good performances, and has simple control structure. Hybrid passivity based control of voltage source PWM rectifiers under unbalanced voltage conditions is proved feasible by simulation and experimental results.

Key words： Unbalanced voltage conditions PWM rectifier hybrid passivity based control energy storage function damping injection
