ISSN: 2319-1112 /V2N2:243-248 ©IJAEEE Abstract : To increase the processing speed and decrease the power consumption, the operating voltages of computer microprocessors is reduced below 1.5V. At the same time, it is expected that these processors will require much more current. To keep the distribution losses low at an increased power level, the input current of the new generation of on-board d...

A new multiple-input hybrid energy conversion topology is presented. The proposed topology is capable of combining different energy sources with different voltagecurrent characteristics, while achieving low part number and bi-directional operational. The Multiple-input converters have many applications such as grid connected integrated hybrid generation systems, fuel cells, micro grid-based tel...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract One of the main disadvantages of the buck converter and the interleaved buck converter is the narrow duty cycle which limits the application of the converters for high step-down applications. The interleaved buck converter with high conversion rati...

The buck or step-down DC-DC converter is the workhorse switching power supply topology. It utilizes two switches (two FETS or one FET and one diode) along with an output inductor and output capacitor. Whether you look at a large computer server, a personal desktop or a laptop computer, a cell phone or a GPS unit all will contain a buck converter in one form or another. This paper will discuss t...

We describe a 42 year old man who presented to us with a left lateral chest wall mass of 2 years duration. It has been increasing in size since it was noticed, initially painless but became painful 2 months prior to presentation. No history of trauma to the chest and no cough or haemoptysis. He is a known hypertensive regular on his medications. Examination revealed a left lateral chest wall ma...

The strategy developed for sex determination in skeletal remains is to amplify the highly degraded DNA, by use of primers that span short DNA fragments. To determine sex of unembalmed human cadaveric skeletal fragments from Sokoto, North-western Nigeria, using Polymerase Chain Reaction (PCR). A single blind study of Polymerase Chain Reaction (PCR)-based sex determination using amelogenin gene a...

A novel topology for a soft-switching buck dc– dc converter with a coupled inductor is proposed. The soft-switching buck converter has advantages over the traditional hardswitching converters. The most significant advantage is that it offers a lower switching loss. This converter operates under a zero-current switching condition at turn on and a zero-voltage switching condition at turn off. It ...

In this work a buck converter model for multidomain simulations is proposed and compared with a stateof-the-art buck converter model. In the proposed model no switching events are calculated. By avoiding the computation of the switching events in power electronic models the processing time of multi-domain simulations can be decreased significantly. The proposed model calculates any operation po...

This paper deals with the modeling of bond graph buck converter systems. The bond graph formalism, which represents a heterogeneous formalism for physical modeling, is used to design a sub-model of a power MOSFET and PiN diode switchers. These bond graph models are based on the device’s electrical elements. The application of these models to a bond graph buck converter permit us to obtain an in...
