NON-CONTACT POWER SUPPLY SYSTEM

摘要

PURPOSE: A contactless feeding system is provided to reduce the power consumption of a feeding device during a standby state by removing a coil which is included in a load device. CONSTITUTION: A feeding device(A) transmits high frequency power. A power transmission part(1) includes a first coil(10) for transmission and an inverter circuit(11) which applies a high frequency current to the first coil. An oscillating part(2) includes a first coil for a signal(20) and an oscillation circuit(21). A signal detection part(3) detects a signal which is received from the first coil for a signal. A control part(4) controls the power transmission part according to a signal which is detected from the signal detection part.
