This paper presents a new Power Electronic Building Block (PEBB) designed to facilitate the implementation of different power converter topologies. The proposed PEBB consists of two diodes and two transistors and it can be used to implement the most relevant power converter topologies, due to its modularity. The addition of the two diodes is an exclusive feature of the new PEBB, which permits t...

This paper presents concept of single phase matrix converter. Single phase matrix converter (SPMC) performs a function such as frequency changer, rectifier, inverter; chopper. This reduces the need for new converter hardware. Pulse width modulation (SPWM) techniques are used to calculate the switch duty ratio to synthesis the output. The simulation of converter is carried out in MATLAB/SIMULINK...

This paper presents, linear peak current mode controller for the control of DC/DC buck converter is designed and analyzed. Dynamic equations describing the buck converter are derived and linear peak current mode controller is designed. The buck converter, the voltage mode and current mode controller are modeled and are evaluated by computer simulations. The proposed technique has the advantages...

An averaged model of a coupled-inductor boost converter using the piecewise complementarity model of the converter under sliding motions is obtained. The model takes into account the idealized voltagecurrent characteristic of passive switches (diodes) present in the converter. Because of its lower complexity, the averaged model is more suitable for control design purposes as compared with the l...

Isolated, surviving sacs of everted small intestine were used to characterize ammonia transport in the golden hamster. Jejunal and ileal sacs incubated aerobically in ammonia-free test solution liberated the same quantity of ammonia as did sacs that were filled and immediately emptied of their contents, indicating no significant evolution of metabolic ammonia. Under aerobic conditions, ileal sa...

This paper proposes an implementation of Single Ended Primary Inductor Converter (SEPIC) converter and Voltage Source Inverter for an Induction Motor using Photovoltaic energy as a source. Generally the larger number of drives employed for industrial and commercial applications are induction motor drives. To run such kind of motor from the PV source, it is proposed to have a DCDC converter and ...

A single-phase ac-to-dc converter using threephase modified series-parallel resonant converter is proposed in this paper. The three-phase resonant converter is analyzed using Fourier series approach. The design curves for a resonant converter of 2.5 kW rating are plotted. The converter components are selected based on the design curves. The converter is simulated for different load conditions u...

In this project presents a new non conventional energy source based bidirectional dc/dc converter for transfer the power in both directions. The nonconventional source of solar energy with Maximum Power Point Tracking is used to avoid the demand of electric power, which is inexhaustible and non pollution .The maximum power point traction is the combination of switch mode converter and Controlle...

1 This work is supported by Philips Research, Briarcliff Manor, NY, through Colorado Power Electronics Center Abstract – Single-switch step-up/step-down converters, such as the buck-boost, SEPIC and Cuk, have relatively high voltage and current stresses on components compared to the buck or the boost converter. A buck-boost converter with two independently controlled switches can work as a boos...

Many fishes are ammonotelic but some species can detoxify ammonia to glutamine or urea. Certain fish species can accumulate high levels of ammonia in the brain or defense against ammonia toxicity by enhancing the effectiveness of ammonia excretion through active NH4+transport, manipulation of ambient pH, or reduction in ammonia permeability through the branchial and cutaneous epithelia. Recent ...
