This paper deals with bifurcation analyses in current programmed DC/DC Boost converter and exhibition of chaotic behavior. This phenomenon occurs due to variation of a set of the studied circuit parameters (input voltage and a reference current). Two different types of bifurcation paths have been observed as part as part of another bifurcation arising from variation of suitable chosen parameter...

A very attractive and relatively simple option to simulate a DC-DC converter is use hybrid model. In this case, the need small simulation steps (as those necessary models carried out at physical level) avoided. Furthermore, unlike averaged state-space models, it has advantage that model valid throughout entire working range of for both conduction modes (continuous discontinuous). By simulating ...

This paper investigates the effect of the variation of duty ratio on the different performance parameters of the three non-isolated dc-dc converters namely buck, boost and buck-boost converter. Five important parameters dependent on the duty ratio have been identified namely output voltage, output current, effective impedance at the input, minimum inductance and minimum capacitance for continuo...

This paper presents the design and modeling of DC/DC boost (step-up) converter for Advanced Intelligent Systems using Matlab/Simulink. The steady-state and average-value models for the proposed converter are developed and simulated. This work offers modeling and simulation techniques to analyze and design for an overall efficiency optimization of standard synchronous and asynchronous boost conv...

Quasi-periodic route to chaos is a common feature in DC-DC switching converters like the Boost and the Buck-Boost. A periodic orbit bifurcates into a T torus through a Neimark-Sacker bifurcation, and then, quasi-periodic behavior is obtained. Further changes in the parameters may breakdown such torus resulting in chaotic behavior. Analytical expressions are deduced for the stability character o...

A non-isolated DC/DC converter with high transfer gain is proposed in this paper. The presented converter consists of the switched inductor and three-level converters. The DC/DC power converter is three-level boost converter to convert the output voltage of the DC source into two voltage sources. The main advantages of DC/DC converter are using low voltage semiconductors and high gain voltage. ...

In this paper, Vienna rectifier and Z Source Inverter (ZSI) based Wind Power Conversion System (WPCS) has been proposed with less number of switches to provide high quality power to off grid system. The three phase full bridge converter has six switches for the conversion of AC-DC and also need separate DC-DC boost converter to boost the DC voltage. In the proposed WPCS, three Phase Vienna rect...
