Title:
POWER-SAVING DEVICE
Document Type and Number:
Japanese Patent JP2018110479
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power transmission-side circuit which reduces total power consumption of a DC resonance type system.SOLUTION: A power-saving device is characterized in: detecting whether a hand etc., is in contact with a product, and continuing power transmission as usual when YES, but changing a frequency of a power transmission line from a resonance frequency when NOT. Switching to a low power consumption mode is performed by changing the resonance frequency according to a signal from a device which has very low power consumption, which is a touch sensor, so as to reduce power consumption in an unused state with little increase in total power consumption of the system.SELECTED DRAWING: Figure 1
