A Model Predictive Control for a Four-Leg Inverter in a Stand-Alone Microgrid under Unbalanced Condition

The Power Electronics, Drive Systems & Technologies Conference, 2021
In this study, a model predictive control (MPC) method is used to control a four-leg voltage source inverter in a stand-alone microgrid. The proposed method aims to regulate the voltage of the inverter so that the cost function of the MPC becomes minimum.

Model Predictive Control of a Two-Motor Drive Using a Four-Leg Inverter

International Electric Machines and Drives Conference, 2021
In this paper, a cost-effective four-leg inverter is proposed to independently control two three-phase permanent magnet synchronous motors (PMSM). In this topology, one of the phases of the three-phase PMSM is connected to the midpoint of the dc-link ...

A Study of a 3-Phase Four-Leg Inverter Dynamic Operation

2018 International Conference on Engineering Technology and their Applications (IICETA), 2018
this 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.

Hybrid control strategy of double closed-loop and improved repetitive control based on three-level three-phase four-leg inverter

2024 6th International Conference on Energy Systems and Electrical Power (ICESEP)
Three-level three-phase four-leg (3L3P4L) inverter is widely used in uninterruptible power supply because it can provide a path for zero-sequence current components and realize operation under asymmetric load conditions.
