誘導電力伝送回路
Document Type and Number:
Japanese Patent JP5054113
Kind Code:
B2
Abstract:
To provide an induced power transmission circuit that transmits, from a transmission antenna (1) connected to a power supply circuit, an AC power having an angular frequency omega to a spaced reception antenna (2) with an excellent efficiency, thereby transmitting it to a load circuit. The induced power transmission circuit comprises a circuit the two ends of which are coupled by a capacitor (C1) and in which the power supply circuit is connected in series to a midway port (1) (P1) of the transmission antenna (1) having an effective self-inductance L1; and a circuit the two ends of which are coupled by a capacitor (C2) and in which the load circuit is connected in series to a midway port (2) (P2) of the reception antenna (2) having an effective self-inductance L2; wherein for a coupling coefficient k of the electromagnetic induction between the antennas and for a phase angle beta having an arbitrary value, the angular frequency omega is set to the square root of the reciprocal of a value of L2×C2×(1+k*cos(beta)), the output impedance of the power supply circuit is set to approximately komegaL1*sin(beta), and the input impedance of the load circuit is set to approximately komegaL2*sin(beta). There is also provided an impedance converting circuit that converts the circuit impedances.
