Submitted: Jun 8, 2013; Accepted: Jul 17, 2013; Published: Jul 25, 2013 Abstract: In this paper different types of converters based on different types of switching cells have been studied and designed. The analysis of each converter has been carried out. The main objective of analysis is to find out the advantages and disadvantages of each converter and to find the converter suitable for the gi...

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 and good efficiency. And with a careful design of the converter the filter capacitances can be made small enough so that film capacitors may be used. Thus the converter mean time between failures can be made as high as that of the solid-sta...

A new transformerless buck–boost converterwith simple structure is proposed in this study. Comparedwith the traditional buck–boost converter, the proposedbuck–boost converter’s voltage gain is squared times of theformer’s and its output voltage polarity is positive. Theseadvantages enable it to work in a wider range of positiveoutput. The two power switches of the proposed buck–boost converter ...

Environmental friendly solutions are becoming more prominent than ever as a result of concern regarding the state of our deteriorating planet. This paper presents a new DSP controller based Switching configuration of hybrid Distributed Energy Generators (DER) with a single input DC-DC Buck-Boost converter, based on their availability . This configuration allows the two sources to supply the loa...

The occasion of a retiring presidential address seems like a time to look back, take stock and perhaps look ahead. Institutionally, it was an honor to serve as President of the Association and I want to thank my teachers and predecessors for guidance and advice and my fellow o¢ cers and our publisher for their work and support. To all of the members who answered my calls to chair or serve on th...

This paper presents a multilevel converter with regeneration capability. The converter uses several power cells connected in series, each working with reduced voltage and with an active front end at the line side. This paper presents the following: 1) the control method of each cell; 2) the use of phase-shifting techniques to reduce the current and voltage distortion; and 3) criteria to select ...

In this paper, a 0.18-V input three-stage charge pump circuit applying forward body bias is proposed for energy harvesting applications. In the developed charge pump, all the MOSFETs are forward body biased by using the inter-stage/output voltages. By applying the proposed charge pump as the startup in the boost converter, the kick-up input voltage of the boost converter is reduced to 0.18 V. T...

Domestic service robots are currently powered by the mains electricity. The growing multiplication of such devices negatively impacts our environment. In this study, we show the feasibility of harvesting energy from natural light in an indoor environment. The design of the harvester is carefully carried out using an experimental characterisation of several solar panels, while the boost converte...
