Experimental detection of bifurcations and sliding in DC-DC power converters
2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003This paper is concerned with some particular nonlinear phenomena that can arise in piecewise-smooth feedback systems. Experimental results for detecting bifurcations and sliding in DC-DC power converters are presented and they confirm what theory predicted in earlier works.

This chapter deals with three main topologies of DC/DC converters: buck, boost, and buck-boost. After a short presentation of linear conversion drawbacks, fundamentals on switching conversion are explained. The DC/DC converters are analyzed in continuous and discontinuous operating mode and main parameters as gain, critical inductance, and load voltage

Power improvement of piezoelectric transformer based DC/DC converter
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012In this paper a novel strategy to increase the power of piezoelectric transformer (PT) by using a cooling system is presented. A thermal pad is directly attached to a PT to dissipate the heat and enhance the power capacity. In a piezoelectric ceramic the heat increase quickly when the vibration velocity become too large.

DC-DC power converter for monolithic implementation
Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2002With the increasing drive towards compactness and portability, there is a need for high power density power supplies. This paper presents a power supply suitable for monolithic implementation. A 5 V-10 V boost converter has been designed using 1.2 /spl mu/m Hewlett-Packard and 0.25 /spl mu/m SOI MITLL CMOS process technology.

A Nonlinear Control for DC–DC Power Converters
IEEE Transactions on Power Electronics, 2007A nonlinear control is proposed and its application to the regulation of the dc-dc converters of the boost and buck types is investigated. The proposed controller, which assumes the exponential form of the linear multiloop controller, provides an additional tuning parameter which can used to modify the output response.

A power converter is basically provided with at least three switching circuits, at least one power source, at least one load, and a resonant circuit. Input terminals of the switching circuits are connected to either the at least one power source or the at least one load, and output terminals of the switching circuits are electrically serially connected

Mathematical modeling of power DC/DC converters
2004 International Conference on Power System Technology, 2004. PowerCon 2004., 2005Mathematical modelling of power DC/DC converters is a historical problem accompanying with the development of the DC/DC conversion technology since 1940's. The traditional mathematical modelling is successful to describe fundamental converters, but not available for complex structure converters since the differential equation order increases very high.
