Photovoltaic (PV) array assisted water pumping systems are gaining more popularity in household and agriculture applications in absence of grid power. In this paper, the investigations on performance of a PV based multilevel voltage source inverter (VSI) powered Induction motor (IM) based water pumping system. The neutral point diode clamped (NPC) inverter with sinusoidal pulsewidth modulation (SPWM)...
This paper presents a modified bridgeless Landsman converter-fed power factor correction (PFC) for light emitting diode (LED) driver. The application is targeted for high brightness (HB) projection applications with brightness control of high brightness red-green-blue (HB-RGB) LEDs. The pulse width modulation (PWM) technique is used for current control to achieve effective brightness control of LED...
DC microgrid provides the horizontal infrastructures to integrate distributed generation (DG) and loads. The protection of DC microgrid is a quite challenging task. Unlike conventional AC system, the DC system cannot survive or sustain high-magnitude fault currents. The nodal analysis with overcurrent (NAOC) scheme is proposed for fault detection and isolation in the service main and DC bus without...
This paper presents back tracking search algorithm (BSA) to for a day-ahead optimal scheduling of a micro grid that is comprised of a wind turbine, a photo voltaic array, battery storage, a fuel cell, a diesel generator and a micro turbine. The proposed solution methodology incorporates two perspectives of the problem. First, fuzzy logic system is developed to obtain the scheduling of battery storage...
