A novel buck/boost/buck-boost three-input DC/DC converter
IECON 2011 - 37th Annual Conference of the IEEE Industrial Electronics Society, 2011In hybrid renewable power systems, the use of a multiple-input dc/dc converter (MIC) leads to simpler circuit and lower cost, compared to the conventional use of several single-input converters. This paper proposed a novel three-input buck/boost/buck-boost converter, which can be applied in all kinds of input voltage application.

Buck-boost integrated forward converter
2005 European Conference on Power Electronics and Applications, 2005An integrated converter is a synthesized converter based on the overall system integration, which is simplified by the system objective and can implement the system functions similar to the discrete converters. An integrated converter consists of converter sets; each converter set has a special function defined by the designer.

A novel isolated buck-boost converter
INTELEC 2009 - 31st International Telecommunications Energy Conference, 2009This paper proposed a novel Isolated Buck-Boost PWM DC-DC converter circuit. The topology which merged buck-boost mode with flyback mode can share the transformer and switch. Not only isolated buck-boost mode current but also flyback mode current added on the one output current of the converter because the topology merged buck-boost mode with flyback ...

QUASIPERIODICITY AND CHAOS IN THE DC–DC BUCK–BOOST CONVERTER
International Journal of Bifurcation and Chaos, 2000This paper is concerned with the study of nonlinear phenomena in a closed loop voltage-controlled DC–DC Buck–Boost converter when suitable parameters are varied. The dynamics is analyzed using both the continuous-time model and the numerically computed stroboscopic map. The analysis of the one-dimensional bifurcation diagram shows that Neimarck–Sacker
