“…With this set of parameters, the converter is supposed to operate in CCM with a duty cycle of 0.6544 in the steady state. Thus, as the steady-state duty cycle exceeds 0.5, the system becomes unstable when it is under current-mode control [8]. A chaotic attractor from the Poincaré map of this system is shown in Fig.…”

In this paper, a buck-boost dc/dc converter under a typical current-mode control is studied. The existence of chaos is proven theoretically in this system. The proof consists of showing that the dynamics of the system is semiconjugate to that of the one-sided shift map, which implies positive entropy of the system and hence chaotic behavior. The essential tool is the horseshoe hypotheses proposed by Kennedy and Yorke, which will be reviewed prior to the discussion of the main finding. Moreover, the existence of chaos is also illustrated in the light of homoclinic intersections of stable and unstable manifolds.

“…Various techniques can be found in literature to obtain a linear continuous Time Invariant (LTI) model of a DC-DC converter. The most well-known methods are: Current injected approach, circuit averaging and state space averaging Kislovski et al, 1991;Mohan and Undeland, 2007;Vorpérian, 1990). Averaging and small signal linearization is key steps of these methods.…”

“…The current injected method (Kislovski et al, 1991;Mohan and Undeland, 2007) can do the job of modeling in either CCM or DCM. Circuit averaging gained a lot of attention recently due to its generality (Hren and Slibar, 2005).…”

In this paper, first software is developed to extract dynamical model of famous dc-dc converters because at the time of this writing there is no software to obtain the converter's dynamical equation analytically. Using commercial softwares like MATLAB ® , only graphical frequency response of system can be obtained. Software developed here can give both analytic equation and graphical frequency response of system. Based on the dynamical equation given by software problem of controller design for two converters is studied as example. Designed controller is tested via Simulation. Authors used the developed software to train control engineering concepts to electrical engineering students. It is seen that using a power electronics converter as plant, increase electrical engineering students interest to learn control engineering concepts. Beside the educational use, developed software can be used to design controller for industrial converters.

This paper studies dynamics and control of a converter with advantages like: High step down gain, common ground between input and output terminal, positive output voltage and low voltage stress on switches and diodes. However, gate drive circuitry is more complex due to floatation of MOSFET sources. Converter's small signal model is extracted using State Space Averaging (SSA). A controller is designed for the obtained model using MATLAB ® control system toolbox. This paper shows that control of converter can be done using a simple I-type controller. This is another advantage for studied topology.
