Minimum Loss Discontinuous Pulse-Width Modulation Per Phase Method for Three-Phase Four-Leg Inverter [PDF]

open access: yesIEEE Access, 2020
The three-phase four-leg inverter (TPFLI) provides unbalanced voltage to a load or injects unbalanced current to a grid to compensate unbalanced current. However, it has a high switching loss because of the fourth leg. This paper presents a discontinuous

Space vector‐based three‐level discontinuous pulse‐width modulation algorithm

open access: yesIET Power Electronics, 2013
Discontinuous pulse‐width modulation (PWM) techniques result in reduced power loss in voltage source inverters. This study presents the space vector approach to the three‐level discontinuous PWM technique. The switching sequences for four basic types of discontinuous PWM and the implementation are presented.

Dual-frequency discontinuous space vector pulse width modulation for five-phase voltage source inverter with harmonic injection

open access: yesCSEE Journal of Power and Energy Systems, 2019
This paper proposes a dual-frequency discontinuous space vector pulse width modulation (DFDSVPWM) for the five-phase voltage source inverter with harmonic injection. In this modulation, for dual-frequency voltage output and reduction of switching losses, two different zero-vector-inserted modes are flexibly employed by using two types of zero vectors ...
