Title:
IGNITION DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2015/156382
Kind Code:
A1
Abstract:
In the present invention the on-off state of an energy input switching means (20) is controlled such that the maximum value of the discharge current of a capacitor (13), as detected by a primary-side current detection means (24) provided on the grounded side of the capacitor (13), does not exceed a first control value (Y1) obtained in advance from the magnetic saturation of a primary coil (3). Thus, magnetic saturation of the primary coil (3) can be avoided, and the reliability can be improved for an ignition device in which an energy input circuit (6) is installed.
