Modeling and controller design principles for six-switch PWM voltage-source rectifiers have been covered thoroughly in recent studies. In contrast, the control strategies for four-switch PWM VSRs are rarely reported. In order to achieve a high performance control, this paper develops a control oriented dual single-input-single-output model for 4-switch PWM VSRs in a novel non-orthogonal frame. Using...
The modeling, modulation, and control of the three-phase four-switch (TPFS) PWM rectifier are investigated in this paper. Three space vector pulse width modulation methods using different equivalent zero vectors are developed, where sector identification and the trigonometric function are not required. Then, the high-frequency model for the current ripple analysis is proposed, and the effects of three...
