Title:
CAPACITOR EMBEDDED BETWEEN BUSBARS, ELECTRIC POWER DEVICE AND ELECTRIC POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/056873
Kind Code:
A1
Abstract:
Provided are: a capacitor embedded between busbars, whereby it becomes possible to reduce the size of a capacitor to be used in an inverter or the like or eliminate a capacitor to be used in an inverter or the like; an electric power device; and an electric power conversion device. It becomes possible to provide: a capacitor embedded between busbars, which is provided between a pair of opposed busbars and comprises a high-dielectric material having a specific dielectric constant of 50 or more when a voltage of 1000 V is applied at 25°C, and which enables the reduction in size of a capacitor to be used in an inverter or the like or the elimination of the capacitor; an electric power device; and an electric power conversion device.
