The control method of a non-contact electric supply device, and a non-contact electric supply device

Japanese Patent JP6183671

B2

In the present invention, a contactless power supply device comprises: a power supplying device (1) that includes a power supply-side resonant circuit (12), and a primary coil (L1) which is connected to the power supply-side resonant circuit (12); and a power receiving device (2) that includes a power reception-side resonant circuit (21), a secondary coil (L2) which is connected to the power reception-side resonant circuit (21) and which can receive power from the primary coil (L1) using magnetic energy, and a rectifier circuit (22) which rectifies power received at the secondary coil (L2) to generate output power and supplies the same to a load. A contactless power supply device control method uses at least one of the following techniques: a technique in which the primary coil (L1) is electrified using the high frequency current of each of a plurality of test-use drive frequencies, and while the primary coil is being electrified the resonant frequency of resonance characteristics in a state where the primary coil (L1) and the secondary coil (L2) are coupled is specified; or a technique in which on the basis of the output power supplied to the load, the resonant frequency of resonance characteristics while the output power is being supplied in a state where the primary coil (L1) and the secondary coil (L2) are coupled is specified.
