Title
(EN) BOOST DC-TO-DC CONVERTER AND POWER CONVERTER POWERED BY THE SAME
(FR) CONVERTISSEUR ÉLÉVATEUR CONTINU-CONTINU ET CONVERTISSEUR ÉLECTRIQUE ALIMENTÉ PAR CELUI-CI
Abstract
(EN) An object of the invention is to provide a boost DC-to-DC converter capable of changing a boost ratio between an input voltage and an output voltage smoothly. Another object of the invention is to provide a simple power converter for driving a five-phase switched reluctance motor. Two pairs of one reactor and one DC power resource are connected in series with a series switch. Moreover the two pairs are connected in parallel via two parallel switches. Each of the two pairs is short-circuited via the series switch by each of the parallel switches. The five-phase power converter applying five phase voltages to five phase windings of a switched reluctance motor has at least six transistors and six freewheeling diodes. two phase windings of five phase windings having a star connection configuration is turned on simultaneously and turned off simultaneously. One of the two phase windings is connected to a high potential line and the other one of the two phase windings is connected to a low potential line, when two transistors are turned on simultaneously.
(FR) Un objectif de la présente invention est de fournir un convertisseur élévateur continu-continu qui est capable de modifier en continu le rapport d'élévation entre une tension d'entrée et une tension de sortie. Un autre objectif de la présente invention est de fournir un convertisseur électrique simple destiné à attaquer un moteur à réluctance commuté à cinq phases. Deux paires composées d'un réacteur et d'une ressource électrique continue sont connectées en série par un commutateur en série. De plus, les deux paires sont connectées en parallèle par deux commutateurs parallèles. Chacune des deux paires est court-circuitée, via le commutateur en série, par chacun des commutateurs parallèles. Le convertisseur électrique à cinq phases appliquant cinq tensions de phase à cinq bobinages de phase d'un moteur à réluctance commuté possède au moins six transistors et six diodes en roue libre. Deux bobinages de phase sur les cinq bobinages de phase sont dans une configuration de connexion en étoile et sont mis en service et à l'arrêt simultanément. Un des deux bobinages de phase est connecté à une ligne à potentiel élevé et l'autre des deux bobinages de phase est connecté à une ligne à bas potentiel lorsque deux transistors deviennent passants simultanément.
