Title:
WIRELESS POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/125526
Kind Code:
A1
Abstract:
A wireless power transmission device (10) has a switching unit (32) that switches power transmission routes (EL1, EL2) so that a first power is transmitted through the first route (EL1) when a first AC power is output from an AC power supply (12), whereas a second power is transmitted through the second route (EL2) when a second AC power is output from the AC power supply (12). An impedance conversion unit (31) is provided on the second route (EL2) and performs an impedance conversion so that the impedance from the output of the AC power supply (12) to a variable load (22) in the case when the second power is transmitted through the second route (EL2) is approximated to the impedance from the output of the AC power supply (12) to the variable load (22) in the case when the first power is transmitted through the first route (EL1).
