<p><P>PROBLEM TO BE SOLVED: To provide a contactless feed system that implements a contactless feed capable of efficient power transmission even when a coupling efficient is small. <P>SOLUTION: The contactless feed system includes: a contactless power transmission section 3 having three stages of contactless transformers in which four coils 3A-3D are sequentially juxtaposed at predetermined intervals between adjacent coils (3A, 3C), (3C, 3D), (3D, 3B), and closed circuits formed by the coils 3C, 3D and capacitors C5, C6, respectively, are resonance circuits; a power conversion device 1 on one side connected with a DC power supply DC1 to convert a DC output voltage of the DC power supply DC1 to an AC voltage, further connected with the coil 3A of the contactless power transmission section 3 such that the converted AC voltage is applied to the coil 3A, and driven as an inverter; and a power conversion device 2 on the other side connected to the coil 3B of the contactless power transmission section 3, and driven as a converter for converting an AC voltage applied via the coil 3B to a DC output voltage and applying the DC output voltage to a DC load R2. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
