Assessment of Model Predictive Voltage Control for Autonomous Four-Leg Inverter [PDF]
IEEE Access, 2020 The Finite control set model predictive control (FCS-MPC) is recently introduced to control inverters without the modulation stage. The absence of the modulation stage gives an unpredictable performance of the control system.

Control Strategy for Four-Leg Nine-Switch Inverter Under Unbalanced Loads [PDF]
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).

A new control scheme for three-phase four-leg inverter
Dianzi Jishu Yingyong, 2018 In the unbalanced or non-linear load conditions, the ordinary three-phase three-leg inverter can not produce three-phase symmetrical voltage, based on the Simulink simulation platform, this paper presents a new closed-loop control design scheme for three-

A decentralized power injection-based approach for voltage imbalance mitigation in three-phase distribution networks [PDF]
Scientific ReportsThis voltage imbalance in four-wire, three-phase distribution networks gives rise to negative-sequence and zero-sequence voltage components which increases the total apparent power received from the network. This also increases the energy losses from the

Digital Predictive Current Control of a Three-Phase Four-Leg Inverter
IEEE Transactions on Industrial Electronics, 2013 While the classical control techniques for threephase two-level four-leg inverters are based on pulse width modulation or three-dimensional space vector modulation, this paper presents a simple digital current control strategy without the modulation stage.
