The matrix converter (MC) arouses a growing interest because it provides many advantages. On the other hand, the association of these converters in parallel makes the operation of the system operation more reliable and offers the possibility of creating electrical micro-grids. This article presents a parallel association of MCs by droop parallelization technique, which allows the control of several...
This paper presents a new control strategy for a high performance hybrid cascaded H-Bridge HB multilevel converter with integrated series Active Power Filter Stage APFS. Unequal DC voltage sources are used to energise the converter's HBs. This offers increased number of voltage levels using fewer number of series connected HBs. Simple hybrid stair-case/SVM modulation strategy is proposed to synthesise...
This paper explores the possibility of using grid side inverter as an interface to connect energy storage systems. A dual inverter system, formed by cascading two 2-level inverters through a coupling transformer, is used as the testing model. The inverters are named as “main inverter” and “auxiliary inverter”. The main inverter is powered by the rectified output of the wind generator while the auxiliary...
This paper presents the control of three-phase inverters connected to the grid by using the concepts of the instantaneous abc theory and the effective apparent power Se. These concepts allow the control of the three-phase inverter from a phasorial point of view both in magnitude and phase. The regulation of the instantaneous reactive power Q allows the instantaneous control of the phase delay phi...
