This item is printed on demand - it takes 3-4 days longer - Neuware -The control devices/switches in dc-dc converter are not ideal and these control devices are having energy losses which are conduction and switching losses. The switching losses are caused by the overlap of switch voltage and switch current in the switching transition period. Thus, this kind of switching can be referred to as hard switching, which specifies stressful switching behavior of converter switching devices. To overcome the disadvantages of hard switching, the soft switching converters have gained a great research interest. In this soft switching control strategy, the switching loss becomes zero by making either voltage across switch or current through switch is zero. the two-level single input multiple output isolated dc-dc converter is proposed for generating 2n-1 outputs where 'n' is number of legs, to reduce the space occupied by individual dc-dc converter systems. The efficiency of the proposed single input multiple output two-level isolated dc-dc converter has been compared with existing single input multiple output two-level dc-dc converter to realize the proposed work. 52 pp. Englisch.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - In the isolated dc-dc converters, there is an AC link which requires the realization of soft switching of control switches. The two-level voltage at the AC link demands more filtering requirement. To overcome this disadvantage, multi level dc-dc converter topologies are being used for the past few years. These topologies reduce size and cost of the filter due to staircase shaped output voltage waveform. These topologies required more number of control switches and these switches operate under high switching frequency in order to reduce requirement of filter. Thereby, the overall switching losses get increased enormously and finally decrease the efficiency of a system. Hence, there is a necessity to develop soft switching controlled multi level isolated dc-dc converters. In this book, a five level isolated dc-dc soft switching converter has been proposed. This converter generates five- level voltage waveform in the primary side of high frequency transformer hence, the size of dc output filter is reduced. The proposed converter has been implemented using FPGA controller and its performance is tested through simulation and experimentation.…
