A new space vector modulation strategy for common mode voltage reduction [in PWM invertors]
PESC97. Record 28th Annual IEEE Power Electronics Specialists Conference. Formerly Power Conditioning Specialists Conference 1970-71. Power Processing and Electronic Specialists Conference 1972, 2002In this paper, the impact of the inverter modulation strategy on common mode conducted emissions is addressed. Whereas typically passive filter designs are used to mitigate the common mode current produced by the inverter, active filtering is proven to greatly reduce common mode conducted emissions due to the modulation of the power converter.

Operating voltage pulse width modulated (PWM) inverters in the overmodulation region extends their voltage and power range and improves their dynamic performance. This paper is a contribution to the extension of the operating range of the classification algorithm for the implementation of space vector modulation (SVM) in the pulse dropping region.

TELESCON 2000. Third International Telecommunications Energy Special Conference (IEEE Cat. No.00EX424), 2002
This paper presents a novel PWM control scheme for three phase inverters. Compared to the traditional carrier based PWM control scheme, the new strategy is able to reduce the power semiconductors' switching frequency to 66.7%, and to increase the amplitude of the inverter output voltages to 115.47%.

A three-phase PWM strategy using a stepped reference waveform (invertor drives)
IEEE Transactions on Industry Applications, 1991The theoretical derivation of a carrier-based three phase pulse-width-modulated (PWM) technique for invertor drives using a stepped reference waveform is presented. The reference waveform is divided into 30 degrees intervals, with each interval being controlled individually to control the magnitude of the fundamental harmonic.

Multi channel PWM power invertors integrated in a switching power supply circuit
IEEE Transactions on Consumer Electronics, 1989A description is given of a PWM (pulse-width modulated) power inverter circuit integrated into a conventional switching power-supply circuit. The output current of the switching power supply is distributed to several output loads by a time-sharing scheme using a PWM switching network that uses input voltage values to determine which load is energized ...
