Abstract

Three control strategies that can be applied to a three-phase AC-DC converter under unbalanced input voltage condition are discussed. Analytic solutions are given on the a-b-c frame, and are very simple, direct and Intuitive. All of the strategies guarantee sinusoidal input currents. All the control functions, including decoupled current control and PWM, are implemented on the a-b-c frame. Accordingly, the controller is very simple and robust. The proposal is verified by simulation and experiments on a prototype operating at 15 kHz
