Patent number: 8164925Abstract: [Problems] To provide a non-contact power feeder that is high efficient and high power factor and has no load 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. The capacitance Cp is set to Cp?1/{2?f0×(x0+x2)} and the capacitance Cs converted to the primary side is set to Cs?(x0+x2)/{2?f0×(x0×x1+x1×x2+x2×x0)}, where f0 is the frequency of the power supply, x1 is a primary leakage reactance of the primary winding 1, x2 is a secondary leakage reactance of the secondary winding 2 converted to the primary side and x0 is an excitation reactance converted to the primary side. By setting Cp and Cs to the above values, the transformer of the non-contact power feeder is substantially equivalent to an ideal transformer. If it is driven by a voltage type converter, the output voltage (=load voltage) becomes substantially constant voltage regardless of the load.Type: GrantFiled: August 7, 2006Date of Patent: April 24, 2012Assignee: National University Corporation Saitama UniversityInventors: Shigeru Abe, Hiroyoshi Kaneko
