This paper proposes a space vector modulation based dc-link capacitor voltage balancing technique for a five-level multiple-pole multilevel diode-clamped (M2DCI) inverter. The new five-level inverter contains lesser number of clamping diodes compared to the conventional five-level diode-clamped inverter (DCI) topology and does not require any extra balancing circuits to maintain balanced voltages...
Flexible active and reactive power injection to the grid is one of the requirements of medium-scale PV power plants (PVPP). Due to the high penetration of installed distributed generation (DG) units to the power system, the flexible active/reactive power control capability is necessary for medium-scale PVPPs in order to maintain the power quality and reliability of the power system. A three-dimensional...
This paper introduces an Indirect Matrix Converter (IMC)-based Unified Power Quality Conditioner topology for a Photovoltaic (PV) system and sensitive load, with enhanced Power Quality functionalities. In particular, the proposed system is able to compensate grid voltage sags, swells and harmonics in the sensitive load, and non-linear load current harmonics in the Low-Voltage (LV) grid, in addition...
