Title:
NON-CONTACT POWER SUPPLY DEVICE, PROGRAM, CONTROL METHOD FOR NON-CONTACT POWER SUPPLY DEVICE, AND NON-CONTACT POWER TRANSMISSION SYSTEM
Document Type and Number:
Japanese Patent JP2017216815
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To supply stable power regardless of a relative positional relation between a primary side coil and a secondary side coil.SOLUTION: A frequency control unit 232 adjusts the magnitude of output power by performing control so that frequencies of first drive signals G1 to G4 are varied discretely. A phase difference control unit 233 adjusts the magnitude of output power by performing control so that phase differences, phase delays of second drive signals G5 to G8 with respect to the first drive signals G1 to G4, are varied discretely. A determination unit 234 determines a pitch width of a control target value composed of at least one of a frequency controlled by the frequency control unit 232 and a phase difference controlled by the phase difference control unit 233, depending on a variation in a measurement value of a measurement unit 24 at the time of controlling the control target value.SELECTED DRAWING: Figure 1
