Title:
NON-CONTACT POWER FEEDING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/002154
Kind Code:
A1
Abstract:
A non-contact power feeding apparatus (1) according to the present invention is provided with: a power receiving element (41) provided on a power-receiving side device (1B); a power receiving circuit (5) which converts AC power received by the power receiving element to generate a motive voltage (VM), outputs the motive voltage to a motive load, generates a control voltage (VC), and outputs the control voltage to a control load; a power feeding element (31) provided at a power-feeding side device (1A); an AC power source (2) which performs switching between an operation frequency used when driving the motive load and the control load and a stand-by frequency used when driving only the control load, and which supplies the AC power to the power feeding element; frequency sensing units (71, 72, 73) that sense a power receiving frequency of the AC power received by the power receiving element; and an motive power cutoff unit (73) that cuts off the output of the motive voltage when the power receiving frequency is changed from the operation frequency to the stand-by frequency. According to this configuration, when the power-receiving side device is temporarily shut down, the motive load is shut down but a non-contact power feeding is maintained to keep driving the control load, and thus the power-receiving side device can be promptly and smoothly restarted.
