A Direct Digital Technique Implementation of General Discontinuous Pulse Width Modulation Strategy

IEEE Transactions on Industrial Electronics, 2011
This paper presents direct digital technique-generalized discontinuous pulse width modulation (PWM) - a new implementation method for an optimal discontinuous PWM (DPWM) in terms of switching losses of the inverter on an embedded system. At each sampling period, an optimal choice is done in order to clamp one of the three half-bridges.

Soft-switched discontinuous pulse-width pulse-density modulation scheme

2016 IEEE Applied Power Electronics Conference and Exposition (APEC), 2016
This paper presents a soft-switched discontinuous pulse-width pulse-density modulation (PWPDM) scheme to decrease the switching losses of the capacitor-less high-frequency pulsating dc-link (HFPDCL) inverters. The proposed modulation scheme employs both pulse-width modulation (PWM) and pulse-density modulation (PDM) schemes to increase the overall ...

An efficient discontinuous pulse width modulation algorithm for multileg voltage-source converters

2011 IEEE International Symposium on Industrial Electronics, 2011
This paper presents a scalable and effective discontinuous pulse width modulation algorithm for multileg converters. The method can also be used in three- and four-leg voltage-source converters, though its simplicity in comparison to so called vector modulators shows up clearly in systems with more than three legs.
