CONTACTLESS ELECTRICAL-POWER-SUPPLYING DEVICE

摘要

[ABSTRACT] To provide a contactless power transfer apparatus in which a power transmission coil and a power reception coil can commonly be used in a contactless power supply transformer of a plurality of specifications. A power reception coil (C2RS) of a specification of an electrical power of 10 kW and a gap length of 70 mm can be position opposite a power transmission coil (C1NS) of a specification of an electrical power of 1.5 kW and a gap length of 70 mm. Further, a power reception coil (C2NS) of a specification of an electrical power of 1.5 kW and a gap length of 70 mm can be positioned opposite a power transmission coil (C1NL) of a specification of an electrical power of 1.5kW and a gap length of 140mm. When a specification of the power transmission coil and a specification of the power reception coil differ from each other, smaller one of the electrical power of the power reception coil and the electrical power of the power transmission coil is used to supply power. If a gap length of the power transmission coil and a gap length of the power reception coil differ from each other, a gap length of a specification of the power transmission coil is used to supply power.
