Tubes à rayons X Résumé : A novel voltage-bucking/boosting converter, named as KY buck-boost converter (i.e., 2D converter), is presented herein. Unlike the traditional buck-boost converter, this converter possesses fast transient responses, similar to the behavior of the buck converter with synchronous rectification. In addition, it possesses the non-pulsating output current, thereby not only decreasing the current stress on the output capacitor but also reducing the output voltage ripple. Furthermore, it has the positive output voltage, different from the negative output voltage of the traditional buck-boost converter. Above all, there are two types of KY buck-boost converters presented herein. In this paper, the basic operating principles of the proposed converters are first illustrated in detail, and second, some experimental results are offered to verify the effectiveness of the proposed topologies.

Voltage-boosting converter based on charge pump and coupling inductor with passive voltage clamping / Hwu, K.I. in IEEE transactions on industrial electronics, Vol. 57 N° 5 (Mai 2010)  

Public ISBD [article]  inIEEE transactions on industrial electronics > Vol. 57 N° 5 (Mai 2010) . - pp. 1719 - 1727 Titre : Voltage-boosting converter based on charge pump and coupling inductor with passive voltage clamping Type de document : texte imprimé Auteurs : Hwu, K.I., Auteur ; Yau, Y.T., Auteur Année de publication : 2011 Article en page(s) : pp. 1719 - 1727 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Charge pump Coupling industor Multiphase Passive voltage-clamping circuit Voltage boosting Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : A new voltage-boosting converter, combining a charge pump and a coupling inductor, together with a passive voltage-clamping circuit which pumps part of the leakage inductance energy to the output, is presented herein. Therefore, by doing so, the efficiency tends to be flat between the minimum and rated loads, which is similar to the behavior of the KY converter. Moreover, the implementation of the passive voltage-clamping circuit for this converter with multiphase is very easy. In this paper, some mathematical derivations are given first, and second, simulated and experimental results are provided to verify the effectiveness of the proposed voltage-boosting converter topology.
