In this work an ac-dc-ac multilevel power converter is investigated. The developed configuration is composed of one single-phase ac-dc-ac three-leg module and two H-bridges, one of them connected in the shared part of the system to employ multilevel voltages to input and output converter, and the other one connected on the grid side for input overvoltage. The converter is employed in applications...
In this paper, the topology of distribution static compensator (DSTATCOM) with a three-phase four-wire system is modified. The modification concerns with the interfacing filter and DC-link capacitor with a goal of improving the system power factor, stabilizing the system voltages and eliminating the harmonic distortion resulting from nonlinear loads. The modified DSTATCOM has a three-leg inverter...
