Title:
CAPACITOR MODULE
Document Type and Number:
Japanese Patent JP2015138942
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a capacitor module capable of suppressing reduction in power transmission efficiency even if a temperature change occurs.SOLUTION: A resonant capacitor module for use in a non-contact power supply system includes: a capacitance section 2 including capacitors 21 for defining a resonance frequency; and a coil 3 electrically connected to the capacitance section 2 and formed in a winding shape to make mutually neighboring windings 31 shift from a contact state to a disconnected state by a temperature rise. Because an inductance of the coil 3 increases even if the capacitances of the capacitors 21 decrease due to the temperature rise, fluctuation of the resonance frequency is suppressed, so that reduction in power transmission efficiency is suppressed.
