Abstract
(EN)
A converter is provided which is capable of avoiding adverse flow of an electric current from an output side of a voltage to an inductor and having a small loss in the electric power. In a converter 1, the source of an FET 11 and the drain of an FET 12 are connected to one end of an inductor L1 while the source of an FET 13 and the drain of an FET 14 are connected to the other end of the inductor L1. The sources of the FETs 12 and 14 are connected to each other. The cathode and the anode of a diode D3 are connected respectively to the drain and the source of the FET 13. After transition has occurred from a state that the FETs 11 and 13 are OFF to a state that a ON/OFF switching of the FET 11 is allowable and the FET 13 is OFF, the FET 13 is maintained at OFF. During this time, the FETs 11, 12, and 14 are turned ON/OFF individually so that an output electric current is generated that flows through a storage battery 4 between the drain of the FET 13 and the source of the FET 14. After the output electric current has been generated, the maintaining of OFF of the FET 13 is released.

L'invention porte sur un convertisseur qui est apte à empêcher un flux adverse d'un courant électrique depuis un côté de sortie d'une tension vers une inductance et ayant une petite perte dans la puissance électrique. Dans un convertisseur 1, la source d'un FET 11 et le drain d'un FET 12 sont connectés à une extrémité d'une inductance L1 pendant que la source d'un FET 13 et le drain d'un FET 14 sont connectés à l'autre extrémité de l'inductance L1. Les sources des FET 12 et 14 sont connectées l'une à l'autre. La cathode et l'anode d'une diode D3 sont connectées respectivement au drain et à la source du FET 13. Après qu'une transition s'est produite depuis un état dans lequel les FET 11 et 13 sont éteints vers un état dans lequel une commutation d'allumage/extinction du FET 11 est autorisée et le FET 13 est éteint, le FET 13 est maintenu éteint. Durant ce temps, les FET 11, 12 et 14 sont allumés/éteints individuellement de telle sorte qu'un courant électrique de sortie est généré qui circule à travers une batterie de stockage 4 entre le drain du FET 13 et la source du FET 14. Après que le courant électrique de sortie a été généré, le maintien de l'extinction du FET 13 est relâché.
