IEEE International Conference on Compatibility, Power Electronics and Power Engineering, 2019
This paper, a model predictive control (MPC) based primary control strategy is proposed for parallel three-phase four-leg inverters in islanded AC microgrids. To regulate the frequency and voltage in the AC microgrid, a cascaded control structure is used.

Modified selective harmonic elimination employed in four-leg NPC inverters
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014Three-phase four-leg neutral point clamped (NPC) inverter is more suitable in dealing with all sort of the loads especially unbalanced/nonlinear due to harmonics issues. Most control strategies applied on four-leg NPC are classified as high switching frequency lead to high power losses and low efficiency.

A Study of a 3-Phase Four-Leg Inverter Dynamic Operation
2018 International Conference on Engineering Technology and their Applications (IICETA), 2018this paper deals with an analysis and study of 3P4L-VSI using the 3D-SVPWM technique. The analysis adopts the average large signal model. The work intended to show the ability of this inverter to overcome the challenge of feeding unbalanced, nonlinear and continuously changed load with balanced 3-phase voltages.

Concise Modulation Strategies for Four-Leg Voltage Source Inverters
IEEE Transactions on Power Electronics, 2004The continuous, discontinuous pulse-width modulation (PWM) schemes and a novel space vector modulation methodology are proposed in this paper for four-leg dc-ac inverters. Using a space vector definition that includes the zero sequence voltage component and partitioning the feasible sixteen modes into two separate sets - one set having zero sequence ...

Modeling of a four-leg inverter based DSTATCOM for load compensation
2010 International Conference on Power System Technology, 2010This paper derives a generalized mathematical model of a three-phase, four-wire, four-leg voltage source inverter topology for a DSTATCOM application. The four-leg inverter is operated in a current controlled mode by a suitable control strategy, to inject compensator currents in order to achieve harmonic compensation, load balancing and power factor ...

Active Filter Based on Four-Leg Inverter and PQ Theory
2019 21st International Middle East Power Systems Conference (MEPCON), 2019The active power filter and unbalance compensator systems play an important role in power quality enhancement. This paper introduces the active power filter based on the 4-leg inverter for 4-wire applications. This system is capable to filter the source current from both harmonics and unbalance components.
