Title:
POWER TRANSMITTING APPARATUS, POWER TRANSMITTER AND POWER RECEIVER FOR POWER TRANSMITTING APPARATUS AND METHOD FOR OPERATING POWER TRANSMITTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2007/142099
Kind Code:
A1
Abstract:
A power transmitting apparatus (100) is composed of a power transmitting section (30)
and a power receiving section (40). The power transmitting section includes at
least a power converting means for converting direct current power into alternating current
power, and a power transmitting coil (1). The power receiving section includes
at least a load (RL) and a power receiving coil (2). Power is transmitted from the
power transmitting section to the power receiving section by permitting the
power transmitting coil (1) and the power receiving coil (2) to face each other. When
an effective series resistance of one single coil of the facing coils is expressed as
Rw(Ω), an effective series resistance of the coil when the other coil facing
the one coil is short-circuited is expressed as Rs(Ω), and a maximum frequency
at which the one coil satisfies Rs>Rw is expressed as f1(Hz), an output frequency
(fa) of an alternating current power supply (Va), i.e., the power converting
means for the power transmitting section (30), is set at a frequency less than
f1.
