This paper presents the design and simulation of the zero voltage zero current switched non isolated dcdc boost converter. Many applications powered by batteries need high performance, high step up dc-dc converters. When the converter switches are turned on and off at high frequency to meet dynamic and steady state requirements, the losses add on in the converter. When current through the switc...

This paper explains the design of a standalone Solar/ Fuel cell/ Battery hybrid power system which involves the design of individual systems along with the power management circuit. The variation of solar insolation according to the time and the Maximum Power Point Tracking’s (MPPT) Perturb and Observe (P&O) algorithm is considered in the design of solar system. Similarly, the control of fuel f...

High Output Voltage Based Multiphase Step-Up DC-DC Converter topology with voltage doubler rectifiers is presented in this paper. High output voltage is obtained due to the series combination of voltage doubler rectifiers on the secondary side of high frequency transformers. This topology is useful in the application where the output voltage is greater than the input. The two loop control strat...

The design and control of power converters required for DC-DC DC-AC conversions are critical to enhancing durability, reliability, efficiency. interfacing essential conditioning efficient load management. In part 1 this work, a grid supporting control, which makes the photovoltaic-based microgrid operate as current source at same time contribute frequency voltage regulation, is proposed analyse...

A new primary side regulation constant voltage (PSR-CV) two-stage solution is proposed in this paper to avoid low frequency current ripple and to maintain high power factor, low cost compared with currently single stage and conventional three-stage solution in analog LED dimming or non-dimming application. PSR-CV is employed in primary side to achieve high power factor, simple circuit combined ...

This paper describes an investigation into the development of a new generation of threephase rectifier, used to power telecommunications equipment. Traditionally, the topology used is a single-phase two-stage design, with a boost converter at the input to the first stage and an isolated dcdc converter making up the second stage. The boost converter provides power factor correction which is nece...

Fuel cells are new alternative energy resource that has a great promise for distributed generation and electric vehicle application. However, fuel cells have a slow response due to their slow internal electromechanical and thermodynamic response. To optimize the fuel cell system performance, a fuel cell DC-DC converter with an appropriate controller which can regulate the power flow and automat...

An intramolecular Diels-Alder (IMDA) reaction was observed at room temperature between an allyl group and a chloroanthracenyl group that were both bonded to the vinylidene ligand of the cationic ruthenium complex [Ru]dCdC(CH2CHdCH2)CH(CH2CHdCH2)(C14H8Cl) (6; [Ru] ) Cp(PPh3)3Ru). The vinylidene ligand functions as a mediator to bring the allyl and the chloroanthracenyl groups in proximity for th...
