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...

Least-Mean-Squares (LMS) based mixed-signal scheme for self-calibration of pipelined Analog-Digital Converter (ADC) is proposed. The technique uses an elegant continuous reference update algorithm to correct for gain errors and offset errors in a pipeline stage with minimal area and power overhead. Simulation results show the effeciency of the scheme for resolution of greater than 13bits in a C...

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...

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...

This article proposed a novel topology of dynamic voltage regulator using transformer and PWM multi-level AC/AC converter. In this paper for finding the best value of duty ratio for switches to minimize the THD, the GA algorithm has been used and THD output voltage is assumed to be fitness function. The proposed voltage regulator employs multi-level AC/AC converter to generate compensation volt...
