Presently, the neutral-point potential offset is an inherent problem for three-level converters
on three-phase four-wire active power filters. The conventional three-dimensional space …

This article proposes a three-phase three-level cascaded H-bridge (CHB) based shunt
active power filter (SAPF) for the management of peak power demand and the mitigation of …

The integration of the distributed generation to the unbalanced loads or the grid requires a
three‐phase four‐wire inverter. The three‐phase four‐wire inverter could be of three‐leg or …

By analyzing the current equivalent circuit of unbalanced load, the mathematical model of
the three-phase four-wire energy storage converter in the dq0 coordinate system is …

The paper discusses an issue of the voltage balancing in the intermediate DC circuit of a
three-level converter system for a smart grid application. A combination of two methods of …

The three-phase four-wire three-level neutral-point-clamped shunt active power filter (NPC-
SAPF) is considered as an effective way to compensate harmonics generated by nonlinear …
