Title (EN) IGNITION DEVICE
(FR) DISPOSITIF D'ALLUMAGE
(JA) 点火装置
Abstract:
(EN) An ignition device (10) is equipped with: a primary coil (11) in which a connection point (14) between a first winding (11a) and a second winding (11b) is connected to a power source (90); a secondary coil (21) which is magnetically coupled to the primary coil; a first switch (31) which is connected in series with the first winding; a second switch (32) which is connected in series to the secondary winding on the opposite side thereof from the connection point; a third switch (33) which is connected in series with the second switch; a diode (44) in which the anode thereof is connected between the second and third switches, and the cathode thereof is connected to the connection point; and a switch control unit (60) for controlling the switching of each switch.
(FR) L'invention concerne un dispositif d'allumage (10) équipé : d'une bobine primaire (11) dans laquelle un point de connexion (14) entre un premier enroulement (11a) et un second enroulement (11b) est connecté à une source d'alimentation (90) ; d'une bobine secondaire (21) qui est couplée magnétiquement à la bobine primaire ; d'un premier commutateur (31) qui est connecté en série avec le premier enroulement ; d'un deuxième commutateur (32) qui est connecté en série à l'enroulement secondaire sur le côté opposé de celui-ci à partir du point de connexion ; d'un troisième commutateur (33) qui est connecté en série avec le deuxième commutateur ; d'une diode (44) dont l'anode est connectée entre les deuxième et troisième commutateurs, et dont la cathode est connectée au point de connexion ; et d'une unité de commande de commutation (60) destinée à commander la commutation de chaque commutateur.
(JA) 点火装置(10)は、第1巻線(11a)と第2巻線(11b)との間の接続点(14)に電源(90)が接続される1次コイル(11)と、1次コイルと磁気的に結合される2次コイル(21)と、第1巻線と直列に接続された第1スイッチ(31)と、第2巻線に対して接続点と反対側に直列に接続された第2スイッチ(32)と、第2スイッチと直列に接続された第3スイッチ(33)と、第2スイッチと第3スイッチとの間にアノードが接続され、カソードが接続点に接続されたダイオード(44)と、各スイッチの開閉制御を実行するスイッチ制御部(60)と、を備える。
