Understanding the three and four-leg inverter Space Vector [PDF]

2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016
This paper shows a new point of view of the classical voltage space vectors and its implications on three and four-leg converters. It is easy to find in the literature, authors using bi-dimensional and threedimensional representations of the converter states. Nonetheless, the literature rarely specifies what these spaces represent.

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

Topology Optimization Analysis of Leakage Current Suppression in Three-Level Four-Leg Photovoltaic Grid-Connected Inverter

IEEE Access, 2023
The grid-connected non-isolated photovoltaic inverter system suffers from the leakage current, which increases the loss of the system, and the grid-connected current harmonics impact the normal operation of the equipment.
