Tubes à rayons X Résumé : This paper proposes a passivity-based control (PBC) strategy for single-phase pulsewidth-modulated current-source inverters feeding a resistive load. In this strategy, it is required to estimate the load resistance and the inductor-current reference. However, the estimation accuracy depends on the inductance value when the load resistance and the inductor-current reference are estimated using an existing adaptive algorithm. In this paper, it is shown that the inductor-current reference estimation is possible at the expense of a constant reference function for the inductor current. In addition, the design of inductor and the sensitivity of the output voltage to the value of output capacitor used in the controller are studied extensively through the steady-state analysis of the proposed PBC. It is also shown that even very large values of the estimation error do not give rise to significant change in the output-voltage amplitude. Computer simulations and experiments are presented to verify the theoretical considerations.

A three-level hysteresis function approach to the sliding-mode control of single-phase UPS inverters / Kukrer, Osman in IEEE transactions on industrial electronics, Vol. 56 N° 9 (Septembre 2009) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 56 N° 9 (Septembre 2009) . - pp. 3477-3486 Titre : A three-level hysteresis function approach to the sliding-mode control of single-phase UPS inverters Type de document : texte imprimé Auteurs : Kukrer, Osman, Auteur ; Komurcugil, Hasan, Auteur ; Doganalp, Alper, Auteur Article en page(s) : pp. 3477-3486 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Three-level  hysteresis  Sliding-mode  control  UPS  Inverters Index. décimale : 621 Ingénierie mécanique en général. Technologie nucléaire. Ingénierie électrique. Machinerie Résumé : A new approach to the sliding-mode control of single-phase uninterruptible-power-supply inverters is introduced in continuous time. A three-level hysteresis sliding function is used to directly control the inverter switches, with the result that a transistor is switched during a half-cycle while it remains either on or off during the other cycle. An expression is derived for the predicted switching frequency. The performance of the proposed control method has been tested through computer simulations and experiments under different loads (a resistive load and a diode bridge rectifier load). Simulation and experimental results verify the correct operation of the proposed control strategy. In addition, the switching frequency prediction is seen to be quite accurate.
