Title:
NON-CONTACT POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/121222
Kind Code:
A1
Abstract:
Disclosed is a non-contact power supply system wherein power is transmitted by means of a magnetic field resonance system from a power transmission device, which is provided with a power transmission-side resonant circuit, to a power reception device, which is provided with a power reception-side resonant circuit. The power transmission device detects, at the time of transmitting the power, a load in the power transmission, and stops the power transmission in the cases where detection results deviate from a predetermined normal range. In the power reception device, a power stabilization circuit (270) that maintains output power of the power reception circuit constant is provided between a load circuit (280) and a power reception circuit (230) that outputs power toward the load circuit on the basis of power received by the power reception-side resonant circuit.
