Quasi-Z-source inverters (qZSIs) are becoming a powerful power conversion technology in photovoltaic (PV) systems because they allow energy single stage operation. However, can cause system resonances and reduce damping, which may lead to instabilities. These stability problems well known grid-connected voltage source converter but not quasi-Z-source inverter (qZSI)-based PV systems. This paper...

Brushless direct current motors (BLDC) are prominent due to their high efficiency and less maintenance. However, BLDC motor applications limited the requirement of a complex controller, existence torque ripple, cost. This research work describes comparative analysis different control strategies ripple reduction in it discusses various topologies viz. cuk converter, simple voltage modulator sche...

Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...

decentralized control strategies are popular candidates in microgrids control because of their reliability and performance. conventionally, droop control (as a main decentralized strategy) is been utilized in order to prevent permanent droop of voltage and frequency after change in loads and also to share generated power between distributed generation units. in this paper, a new droop control s...
