This paper presents a simple input-constrained current controller for a DC/DC boost converter with stability analysis that considers the nonlinearity of the converter model. The proposed controller is designed to satisfy the inherent input constraints of the converter under a physically reasonable assumption, which is the first contribution of this paper. The second contribution is providing a ...

Most of the power electronic equipments are operated with dc supply. For reliable and stable operation, dc supply should be regulated. The regulation can be performed using buck, boost, Cûk, Sepic, Flyback regulators. Except single phase rectifier with resistive load all other rectifiers input currents are non sinusoidal in nature. This front end current distortion of rectifier converter leads ...

In this paper, a novel converter topology for interleaved high step-down conversion ratio dc–dc converter with low switch voltage stress is proposed. In the proposed converter, two input capacitors are series-charged by the input voltage source and parallel discharged by a new twophase interleaved buck converter topology without adopting an extreme short duty cycle for delivering a much higher ...

DC-DC converters, common in battery-driven, portable, and other high-efficiency systems, can deliver efficiencies greater than 95% while boosting, reducing, or inverting supply voltages. Resistance in the power source is one of the most important factors that can limit efficiency. This application note describes the effects of source resistance, how to calculate efficiency, real-world considera...

Implementation of RFID reader/writer on software defined radio is studied in this paper. The target RFID is ISO18000-3 mode 2 which has 8 reply channels for simultaneous communication with 8 different RFID tags. In the software defined radio architecture, the 8 reply channels are sampled at a single A/D converter and separated by digital down converters, whereas conventional RFID architecture h...

In these modern research areas the Nonlinear Dynamics is a very popular topic, the researchers study the nonlinear behaviour of every system which can be an industrial machine/instrument or a theoretical aspect. Prior researchers already studied the nonlinear dynamics of Current Controlled DC-DC Boost Converter. But the Power Factor Corrected Boost Converter is a circuit which is used in very p...

This paper suggests an isolated dc/dc converter using an unregulated LLC converter for fuel cell applications. The LLC converter operates as an isolated voltage amplifier with a constant voltage gain, and a nonisolated converter installed in the input stage regulates the output voltage under a wide variation of fuel cell stack voltage. By separating the functions, the unregulated LLC converter ...

Based on the traditional indirect matrix converter topology dual input dual output indirect matrix converter is proposed, but the conventional six-switch inverter, used in the singleoutput indirect matrix converter, is replaced by a nineswitch dual output converter. The matrix converter has several advantages over traditional rectifier-inverter type power frequency converters. It provides sinus...

This chapter aims to give a general description of the basic features of a three phase to three phase matrix converter in terms of performance and of technological issues. This chapter does not require to the reader a special knowledge of the matrix converter technology. It is worth noting that the three phase to three phase configuration is just one of the possible direct AC-AC converter topol...
