摘要： PROBLEM TO BE SOLVED: To provide a contactless power supply system allowing high overall efficiency of power supply, cost reduction. and easy control of secondary DC output voltage.SOLUTION: A half bridge inverter 20 is used for a high-frequency AC power supply connected to the primary side of a contactless power transformer 30, and a voltage doubler rectifier 40 is used for DC conversion of secondary-side AC output of the contactless power transformer 30. Although AC output voltage of a half bridge inverter is reduced to a half of that of a full-bridge inverter, output voltage of the voltage doubler rectifier is twice of that of a full-wave rectifier, which makes the overall voltage ratio between inverter input voltage and secondary-side DC voltage nearly equal. Voltage of the contactless power transformer is reduced to nearly a half of that of the prior art, providing advantages in loss reduction of ferrite and insulation.

摘要： PROBLEM TO BE SOLVED: To provide a noncontact feeding transformer which can be made compact and lightweight while ensuring excellent heat dissipation characteristics.SOLUTION: In the noncontact feeding transformer comprising a two-side winding coil where a winding is wound around a wound part between magnetic poles of a core 40, and a housing in which the two-side winding coil is housed, and the housing is attached so that the two-side winding coil thus housed faces other two-side winding coil, the housing includes a resin cover 31 having a space for housing the two-side winding coil, and a fixing plate 32 composed of a nonmagnetic conductive metal material and fixed to the resin cover 31 so as to close the opening thereof. In the noncontact feeding transformer, the fixing plate 32 composed of a nonmagnetic conductive metal material such as aluminum functions as the shield material of magnetic leakage flux, and as a heat dissipation material. Since the heat due to winding resistance loss is transmitted to the fixing plate 32 and dissipated therefrom, temperature rise of the noncontact feeding transformer is limited.

摘要： PROBLEM TO BE SOLVED: To provide a contactless current feeding coil device in which a lead out distance of a lead wire of a coil winding can be shortened without impairing magnetic shielding effect of a magnetic shielding plate.SOLUTION: The contactless current feeding coil device includes a coil body having an H-shaped core 301, a resin case body 101 for accommodating the coil body, and a non-magnetic conductive plate 200 for magnetic shielding and to which the case body is fixed. The case body 101 has a case through hole 103 arranged adjacent to a central line bisecting a gap between parallel magnetic pole sections 302 and 303 of the coil body. The non-magnetic conductive plate 200 has a communication through hole 201 overlapping the case through hole 103. A lead wire of wiring wound around the coil body is lead out while being inserted and passed through the case through hole 103 and communication through hole 201. Leakage magnetic flux distribution of the coil having the H-shaped core is lower at an intermediate portion between both the magnetic poles. Consequently, even though through holes for passing the lead wire are formed in this intermediate portion, the magnetic shielding property of the non-magnetic conductive plate is not impaired.

摘要： PROBLEM TO BE SOLVED: To provide a non-contact power supply device that can share a power transmission coil and a power reception coil among non-contact power supply transformers with multiple specifications.SOLUTION: In a non-contact power supply device, it is possible that a power transmission coil (C1NS) having specifications of 1.5 kW electric power supply power and 70 mm gap length faces a power reception coil (C2RS) having specifications of 10 kW electric power supply power and 70 mm gap length, and a power transmission coil (C1NL) having specifications of 1.5 kW electric power supply power and 140 mm gap length faces a power reception coil (C2NS) having specifications of 1.5 kW electric power supply power and 70 mm gap length.

摘要： PROBLEM TO BE SOLVED: To reduce the size and weight of a power receiving unit of a non-contact power feeder. SOLUTION: The non-contact power feeder includes a planar primary core having a primary coil wound therearound, and a planar secondary core having a secondary coil wound therearound, wherein non-contact power feed is executed from the primary coil to the secondary coil through the opposite plate surfaces of the primary core and secondary core. A coil 50 is wound around a narrow width coil-wound portion 43 between two magnetic pole portions 41, 42 of H-type core 40. A spatial magnetic flux distribution between the primary core and the secondary core depends on the shapes of magnetic pole portions 41, 42, and a magnetomotive force of the coil 50 depends on the following: (magnitude of coil current)×(number of windings). Accordingly, if the shape of the magnetic pole portion 41 and the number of windings of the coil 50 are not changed, the magnetomotive force of the coil 50 does not change even with/without reducing the width of the coil-wound portion 43. On the other hand, when the width of the coil-wound portion 43 is narrowed, the coil length is shortened, and the resistance of the coil 50 is reduced to reduce the weight of the coil 50.

摘要翻译：要解决的问题：为了减小非接触供电器的受电单元的尺寸和重量。解决方案：非接触式馈电器包括具有卷绕在其周围的初级线圈的平面初级铁芯和在其周围缠绕有次级线圈的平面二次铁芯，其中从初级线圈到次级线路执行非接触馈电线圈穿过主芯和次芯的相对的板表面。线圈50缠绕在H型芯40的两个磁极部41,42之间的窄宽线圈卷绕部43上。初级芯与次级芯之间的空间磁通分布取决于磁极部的形状 41,42，线圈50的磁动势取决于：（线圈电流的大小）×（绕组数）。因此，如果磁极部分41的形状和线圈50的绕组数量没有改变，则线圈50的磁动势即使在不减小线圈卷绕部分43的宽度的情况下也不变化。另一方面，当线圈缠绕部分43的宽度变窄时，线圈长度被缩短，并且线圈50的电阻被减小以减小线圈50的重量。版权所有（C）2011 ，JPO＆INPIT
