Model Predictive Control Algorithm for Prolonging Lifetime of Three-Phase Voltage Source Converters

open access: yesIEEE Access, 2023
One of the key goals of power electronics is to reduce losses in three-phase converters in order to increase efficiency and reduce thermal stress, which can lengthen the lifetime of devices. However, the aforementioned studies do not account for the fact

Optimal digital control of a three-phase four-leg voltage source inverter

open access: yesTURKISH JOURNAL OF ELECTRICAL ENGINEERING & COMPUTER SCIENCES, 2016
This paper presents a three-dimensiona (3-D) space vector pulse width modulation (SVPWM) technique via a 4 4 orthonormal transformation matrix that has been used as a new approach in controlling a three-phase four-leg voltage source inverter (VSI). A fully optimal digital control scheme for the closed-loop regulation of the three-phase four-leg VSI ...

Control Strategy for Four-Leg Nine-Switch Inverter Under Unbalanced Loads

open access: yesIEEE Access, 2020
On account of that nine-switch inverter (NSI) cannot supply symmetrical voltages to unbalanced loads, based on the NSI, N-phase leg is added to the neutral points of the loads, which forms a four-leg nine-switch inverter (FLNSI).
