METALLIZED FILM CAPACITOR, INVERTER CIRCUIT FOR ON-VEHICLE DRIVING USING THE SAME, AND AUTOMOBILE THE INVERTER CIRCUIT FOR ON-VEHICLE DRIVING MOUNTED THEREON

摘要

PROBLEM TO BE SOLVED: To solve the problem that a capacitor element breaks in the worst case because the conventional film capacitor is used in the severe temperature condition and may also be used exceeding the thermally allowable value of the film capacitor when it receives all thermal factors.;SOLUTION: Temperature-proof characteristic can be improved by suppressing thermal influence received from the other equipment and heat generating factors of bus bar, adequately mounting capacitor forming components and processing the heat transferred from the external side, and suppressing current density. The film capacitor adaptable to mounting on an automobile can be obtained through improvement in the temperature-proof characteristic and reliability of the film capacitor for the temperature-proof characteristic, by lowering current density not to result in concentration at the shape of the connection bus bar and element bus bar of the film capacitor, and by extending the connection bus bar to enhance the heat radiating property through the layout of the bus bar itself.;COPYRIGHT: (C)2005,JPO&NCIPI
