Optimal digital control of a three-phase four-leg voltage source inverter
TURKISH 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
IEEE 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).
