Carrier-Based Discontinuous PWM Method for Vienna Rectifiers
IEEE Transactions on Power Electronics, 2015Vienna rectifiers, which are nongenerative-boost types of rectifiers, are used in grid-connected applications with a unity power factor such as telecommunication systems and wind turbine systems. These rectifiers are advantageous in that they have low total harmonic distortion and efficiency.

An Optimized Discontinuous PWM Method to Minimize Switching Loss for Multilevel Inverters
IEEE Transactions on Industrial Electronics, 2011This paper presents a novel approach to analyze carrier-based discontinuous pulse width modulation (DPWM) method for multilevel inverters. The separation of the offset into the main and additional components shows the use for analyzing PWM control characteristics of multilevel inverters.

Simplified analysis of PWM converters using model of PWM switch. II. Discontinuous conduction mode
IEEE Transactions on Aerospace and Electronic Systems, 1990For pt.I see ibid., vol.26, no.3, p.490-6 (1990). According to the method of state-space averaging, when a pulsewidth modulation (PWM) converter enters discontinuous conduction mode (DCM), the inductor current state is lost from the average model of the converter.

The analysis and implementation of a discontinuous PWM scheme
Proceedings of 1994 IEEE Applied Power Electronics Conference and Exposition - ASPEC'94, 2002Discontinuous PWM for power converters is compared to more conventional techniques, particularly in terms of deadtime effects and ease of implementation. Harmonic calculations for the different techniques are compared and measured results presented. >

Dynamic Discontinuous PWM for Grid-tied Inverter Applications
2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020This paper proposes a Dynamic Discontinuous PWM (DDPWM) strategy for Grid Tied Inverter applications utilizing 2 level Voltage Source Inverters (VSIs). DDPWM is a version of Generalized DPWM (GDPWM) optimized for usage with full range of operating power factor values and without need for current feedback signals, such that it provides minimal switching

Interleaved PWM with discontinuous space-vector modulation
IEEE Transactions on Power Electronics, 1999This paper describes the effect of interleaved discontinuous space-vector modulation (SVM) in paralleled three-phase systems using three-phase pulsewidth modulation (PWM) rectifiers as an example. At the discontinuous point of the SVM, the phase shift between the switching signals of the paralleled modules generates a zero-sequence excitation to the ...

Analysis of the Discontinuous PWM Strategies Applied to the VSI
2007 International Symposium on Computational Intelligence and Intelligent Informatics, 2007Fully digital AC drives with pulse width modulator inverters are becoming an industrial standard. For PWM inverters the most commonly used is the conventional sine PWM (SPWM). An attempt to improve this carrier based strategy is presented by means of the introduction of discontinuous techniques; such as the dead band PWM (DBPWM) and the modified SPWM ...
