Comprehensive Predictive Control Model for a Three-Phase Four-Legged Inverter
Energies, 2023 This paper presents a comprehensive model predictive control (CMPC) method to control a three-phase four-legged inverter (TP4LI) for PV systems. The proposed TP4LI model aims to predictively model and control switching frequency and higher voltage/current switching to reduce losses. The CMPC model can be operated in four modes, namely standard MPC mode

A State-Space Approach to the Modelling and Control of the Neutral Leg of a Four Legs, Three-Phase Inverter [PDF]
IEEE Transactions on Industrial Electronics, 2022 In this paper, a novel approach to determine the model of an ICNL (Independently Controlled Neutral Leg) is proposed. Based on this model, a cascaded control method is developed to provide a steady neutral point connection for a three-phase four-wire inverter and to balance the two DC capacitors voltages of a split DC-bus.

Minimum Loss Discontinuous Pulse-Width Modulation Per Phase Method for Three-Phase Four-Leg Inverter
IEEE 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

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.
