This paper presents power quality analysis of a distributed generation system consisting of Photovoltaic (PV) – Inverter system as the renewable source connected to a network of Adjustable Speed Drives (ASDs) as the load. A small-scale laboratory consists of Photovoltaic, Inverter, ASDs and loads system was setup. Two power supplies from PV and grid were(More)
Power quality behavior on connecting single phase fed adjustable speed drives to a grid which photovoltaic as the power generation is studied in this paper. A MATLAB/Simulink simulations are performed to investigate the existence of power quality parameter and the system problems that may be resulted from operation of this type of load. The results indicate(More)
—In power electronics efficiency improvement is constantly being sought out through venues such as improved topologies or improved devices. Series Loaded Resonant (SLR) DC-DC converter is a type of soft-switching topology widely known for providing improved efficiency. This paper investigates the efficiency and transient performance of SLR when a new type(More)
Harmonic analysis of input current of single phase uncontrolled rectifier is widely known. However, little has been known about harmonic of the input current of single phase controlled or thyristor rectifier. This paper presents such an analysis using the bridge configuration for the controlled rectifier circuit. Results obtained from mathematical(More)
Numerical analyses of Magnetohydrodynamic (MHD) accelerator using nonequilibrium air plasma are outlined in this paper. Composition of simulated air plasma consists of seven species, N<inf>2</inf>, N, O<inf>2</inf>, O, NO, NO<sup>+</sup> and e<sup>&#x2212;</sup>. The Magnetohydrodynamic Augmented Propulsion Experiment (MAPX) channel designed by NASA is used(More)
Series Loaded Resonant (SLR) converter is a well known topology typically used in kilowatt-range power supplies. The topology may operate in either continuous or discontinuous conduction modes whose switching properties are covered in many power electronic text books. However, information related to the actual converter's efficiency for each conduction mode(More)
