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.

Minimum-loss PWM strategy for 3-phase PWM rectifier

PESC97. Record 28th Annual IEEE Power Electronics Specialists Conference. Formerly Power Conditioning Specialists Conference 1970-71. Power Processing and Electronic Specialists Conference 1972, 1997
In this paper, the conduction and switching losses of a three-phase PWM rectifier are analyzed for various PWM schemes. On the basis of these results, a novel PWM strategy which minimizes the loss of a voltage-fed three-phase PWM rectifier is developed. This minimization results from the following two factors: (a) low switching frequency ratio; and (b)

FPGA implementation of PWM pattern generators [for PWM invertors]

Canadian Conference on Electrical and Computer Engineering 2001. Conference Proceedings (Cat. No.01TH8555), 2002
Pulse width modulation is used in power converters to modulate a reference signal into gating pulses for IGBT switches. This conversion can be carried out using analog circuits or digital circuits, such as DSPs and microcontrollers. A more efficient and faster solution is the use of field programmable gate arrays (FPGA).

PWM conductance control

PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference, 2003
Conductance (or current) control of switching regulators generally uses peak or hysteresis (e.g. LC/sup 3/) controllers, the advantages and problems of which have been widely reported. The behavior of a simple conventional pulsewidth-modulated (PWM) conductance control principle that has been used on space programs is described and analyzed.

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.
