Zusammenfassung: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 【課題】直流共鳴方式におけるシステム全体の低消費電力削減を実現する送電側回路を提供する。【解決手段】製品に手等が接触しているか否かを検出し、是である場合は通常どおり送電をつづけ、否である場合は送電側の周波数を共鳴周波数から変えることを特徴とする。タッチセンサーという非常に消費電力の低いデバイスからの信号に応じて共鳴周波数を変更することによる低消費電力モードへの切り替えを行うことにより、システム全体の消費電力をほとんど上昇させずに、未使用時の電力消費を削減することができる。【選択図】図1
