Title:
CONTACTLESS POWER TRANSMITTING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2014/045875
Kind Code:
A1
Abstract:
Contactless power transmitting equipment (10) is provided with: a primary device (11) having an AC power supply (12), which outputs AC power, and a primary coil (13a) to which the AC power is inputted; a secondary device (21) having a secondary coil (23a), which is capable of receiving the AC power from the primary coil (13a) in a contactless manner, and a load (22); a primary impedance converter (14) that is provided to the primary device (11), and has a fixed impedance; a secondary impedance converter (26) that is provided between the secondary coil (23a) and the load (22) in the secondary device (21), and has a variable impedance; and controllers (15, 28) that variably control the impedance of the secondary impedance converter (26) in response to fluctuations in the impedance of the load (22).
