In these modern research areas the Non-linear 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 ...

In this paper, a comparative analysis on the bifurcative and chaotic behaviour of a current controlled buckboost converter with soft switching and hard switching is performed. The electromagnetic interference generated during hard switching and soft switching of the converter is analyzed. Simulation and measured results show that the total energy is more evenly spread over the frequency band du...

Soft switching of DC-DC converter is done here. This is obtain good efficiency and to reduce the switching losses. Zero voltage switching reduces the switching losses in the circuit. This is done by using boost converter. Soft-switching characteristic of the proposed converter reduces switching loss of active power switches and raises the conversion efficiency. A voltage step-up function and a ...

Buck, boost, and buck-boost converters constitute large class of dc-dc converters used in practice and are interesting nonlinear dynamical systems. It has been shown earlier that various nonlinear phenomena including subharmonics and chaos can be observed in these converters. In this paper we show that with the simplifying assumption that voltage regulation is achieved in high frequency modulat...

A novel bidirectional DC-DC converter is presented in this paper. The circuit configuration of the proposed converter is very simple. The proposed converter employs a coupled inductor with same winding turns in the primary and secondary sides. In step-up mode, the primary and secondary windings of the coupled inductor are operated in parallel-charge and series-discharge to achieve high step-up ...

The boost topology is the most popular topology used in power factor correction circuits. The efficiency and performance of the boost converter depends on the switching frequency affecting the switching losses. At high frequency operations the switching losses of the converter is considerable and decreases the efficiency of the converter. To remove this problem the converter is designed to oper...

In this paper, the dynamics of a DC-DC boost power converter under variable structure control is studied applying bifurcation analysis techniques.

The DS1875 features a pulse-width modulation (PWM) controller that can be used to control a DC-DC converter. The DC-DC converter can then be used to generate the high bias voltages necessary for avalanche photodiodes (APDs). This application note describes the operation of a boost converter that uses the DS1875. Discussion covers the selection of the inductor and switching frequency, and the se...
