Abstract
(EN)
Provided is an ignition device with which it is possible to appropriately increase secondary current by energizing a second primary winding during a discharge period in such a manner that the secondary current does not increase excessively or fall excessively. In the ignition device (10), after a first switching element (1) is turned ON, the first switching element (1) is turned OFF, generating a spark discharge in a spark plug (5), during the spark discharge the second switching element (2) is turned ON, and while the second switching element (2) is turned ON, the first switching element (1) is turned ON/OFF.

L'invention concerne un dispositif d'allumage permettant d'augmenter de manière appropriée un courant secondaire au moyen de la mise sous tension d'un second enroulement primaire pendant une période de décharge, de sorte que le courant secondaire n'augmente pas de manière excessive ou ne chute pas de manière excessive. Dans le dispositif d'allumage (10), après mise sous tension d'un premier élément de commutation (1), le premier élément de commutation (1) est mis hors tension, produisant une décharge par étincelles dans une bougie d'allumage (5) ; pendant la décharge par étincelles, un second élément de commutation (2) est mis sous tension ; et pendant que le second élément de commutation (2) est mis sous tension, le premier élément de commutation (1) est mis sous/hors tension.
