The High-Intensity-Discharge Lamps (HID), consisting of a broad range of gas discharge lamps, are notable for their high luminous efficacy, good color rendering, and long l ife. Metal halide lamps have the best combination of the above properties and are considered the most ideal light sources. Recently, there has been an emerging demand to replace the conventional halogen headlamps with the ne...

A novel floating wave energy converter (BFWEC) with multiple ‘bean shape’ floats and a hydraulic power-take-off system (HPTO) is presented. The overall setup consists of central buoy (C·B.) connected to set around it using lever arm position restrained taut-mooring system. Three configurations BFWEC are proposed four, six, eight number floats. detailed numerical analysis carried out by modeling...

The purpose of this paper is to introduce a different type of converter circuit used to drive switched reluctance motors. It continues with detailed discussion on the resonant converter armed at minimizing or eliminating the transistors switching losses. Finally the drive has been tested on a disc-type reluctance motor for the perfomance and functionality.

Abstract With the advancement of HVDC technology, AC/DC hybrid grid has gradually emerged. The interaction and influence between AC DC have become increasingly prominent, with complementary resonance problem emerging as a hot research topic. In this paper, firstly, phenomenon LCC-HVDC is analyzed in both time frequency domains, method for setting saturation curve converter transformer domain si...

Matrix converter is basically direct three phase to three phase converter and it’s operation is based upon switching pattern of all nine switches, which are available in this converter. The output of ac converter is fed as the input of three phase induction motor. The performance of three phase matrix converter fed induction motor drive is analyzed by the switching pattern obtained by matrix co...

This paper presents a new soft switching flyback-forward PWM converter. The proposed circuit employs an auxiliary circuit to achieve soft switching condition for switches and also absorbs the voltage spikes caused by the leakage inductance of transformers in the converter. In the proposed converter main switch operates at ZVS and the auxiliary switch operates at ZCS. The proposed converter has ...

DC-DC converter is a converter where we are regulating the input voltage to get the desired output voltage which is either greater than or equal to or less than the input voltage with positive or negative polarity. A lot of dc-dc converters are available in the world out of which SEPIC (Single-Ended Primary-Inductor Converter) converter is one of them. To analyse the converter, a lot of techniq...

This thesis aims to identify and analyze the nonlinear behavior in the threephase voltage source converter, which is widely used as an interface converter in a distributed hybrid power system (DHPS). In this system, the converter does not work as a standalone converter but operates as a subsystem that connects to a non-ideal power grid and interacts indirectly with other subsystems via a point ...

An Integrated double buck boost converter is analyzed and the design methodology is made as a high power factor of the power supply for the power LED lamps. The IDBB converter features just one controlled switch and two inductors and is able to supply a solid-state lamp from the mains, providing high power factor. Here with a careful design of the converter, the filter capacitances can be made ...
