In this paper, experimental measurements of four parallel-connected three-phase inverters railway auxiliary converters were carried out. The purpose measurement was to verify the ability parallel co-operation three- phase connected a common bus, verifying starting sequence and power sharing by individual converters. powered high voltage AC source outputs intercon- nected form network. uniform t...

Reliability, Availability and Condition Monitoring (RACM) evaluation has become a critical area of interest for researchers as the output power quality Photo-Voltaic (PV) system depend on reliability its components. In this paper, RACM grid-connected PV systems is presented. For this, Reliability Block Diagram (RBD) technique along with exponential probability distribution function used. The ma...

In order to concentrate the frequency spectrum of output voltage and improve quality grid currents for three-level neutral point clamped inverter with model predictive control, this paper proposes an optimal switching sequence control algorithm. Based on increments neutral-point voltage, is established in αβ frame. Moreover, including tracking, cost function designed simplified by arranging vec...
