Abstract :
Charge control of three-phase buck PWM rectifiers is proposed in this paper. It controls precisely the average input phase currents to track the input phase voltages by sensing and integrating only the DC rail current, realizes six-step PWM, and features simple implementation, fast dynamic response, excellent noise immunity, and is easy to realize with analog circuitry and integrate. The concept, implementation, and design guidelines are addressed. Simulation and preliminary experimental results are given. Also discussed are the potential extension of the proposed control scheme to realize different PWM patterns, and its applications to various three-phase buck rectifier-based systems
