Title:
高周波放電用点火コイル装置
Document Type and Number:
Japanese Patent JP5469229
Kind Code:
B1
Abstract:
An ignition coil apparatus for high-frequency discharge includes: a primary coil that generates and accumulates a flux; a secondary coil that is magnetically coupled to the primary coil so as to generate a predetermined high voltage when energy of the accumulated flux is released and connected at one end to a high-voltage terminal used to supply energy to an external apparatus; a capacitor that is connected to the high-voltage terminal and prevents passing of the high voltage; and an inductor that, together with the capacitor, allows passing of a predetermined frequency component alone. The primary coil, the secondary coil, the capacitor, and the inductor are installed within a same package.
