発明の名称 (英語) NONCONTACT POWER FEEDER
発明の概要(英語) [PROBLEMS] To provide a noncontact power feeder exhibiting a high efficiency, a high power factor, and a nonload dependence. [MEANS FOR SOLVING PROBLEMS] A series capacitor (Cs1) is connected to a primary winding (1) driven by an AC power supply (3), and a parallel capacitor (Cp2) is connected to a secondary winding (2). If the power supply frequency is f0, the primary leak reactance of the primary winding (1) is x1, the secondary leak reactance of the secondary winding (2) in terms of the primary side is x2, and the excitation reactance in terms of the primary side is x0, the Cp value is set to Cp 1/{2f0(x0+x2). The Cs value in terms of the primary side is set to Cs (x0+x2)/{2f0(x0x1+x1x2+x2x0)}. When Cp and Cs are thus set, the transformer of the noncontact power feeder is approximately equivalent to an ideal transformer. If the transformer is driven by a voltage inverter, the output voltage (=the load voltage) is almost constant even if the load value varies. When the load is a resistance load (ZL=R), the power factor of the power supply output is approximately 1 at all times even if the load value varies.
