A Novel PWM Technique With Two-Phase Modulation

IEEE Transactions on Power Electronics, 2007
In this paper, a new two-phase pulse width modulation (PWM) technique is proposed, in which the reference voltage is constructed by three space vectors. At any speed, the peak-to-peak value of the common-mode voltage (CMV) in one PWM cycle can be reduced to one third of the DC bus voltage, even despite of the dead-time effect.

Optimized modulation for PWM rectifiers

2002 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.02CH37309), 2003
An optimized set-up for controlling PWM rectifiers is proposed in this paper. In particular, the control part is based on a predictive estimation algorithm which guarantees the imposed value of the DC link output voltage and, at the same time, a unity power factor behavior at the mains.

Sectionalized PWM (S-PWM): A new multilevel modulation strategy

2008 IEEE International Symposium on Circuits and Systems, 2008
The paper presents a novel multilevel PWM strategy that employs a split section reference waveform with phase-shifted carriers to produce harmonically superior PWM signals. The multilevel PWM switching patterns provide a higher dynamic range than what has been reported in the literature.
