1. A non-contact power supply system comprising:
a power supply device, which includes primary coils arranged on a power supply surface and configured to be excited at an operational frequency; and
a power reception device, which includes a secondary coil configured to induce current using resonance phenomenon based on alternating flux from the primary coils when arranged on the power supply surface, wherein:
the operational frequency that excites the primary coil is set at or in the proximity of a resonance frequency of a resonance system formed when the secondary coil is located at an intermediate position between two of the primary coils that are adjacent to each other.
2. The non-contact power supply system according to claim 1, comprising:
a capacitor connected to the secondary coil;
wherein capacitance of the capacitor is adjusted to set the operational frequency at or in the proximity of the resonance frequency of the resonance system corresponding to the intermediate position.
3. The non-contact power supply system according to claim 1, wherein:
the proximity of the resonance frequency is a frequency region at which output power of the power reception device obtained by the resonance system corresponding to the intermediate position is greater than or equal to an output power of the power reception device obtained by a resonance system formed when the secondary coil is located at a position directly opposed to one of the primary coils.
4. The non-contact power supply system according to claim 1, wherein:
in the proximity of the resonance frequency at the resonance system of the intermediate position, the operational frequency is set to differ from the resonance frequency.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An optical transceiver comprising:
a post-amplifier configured for communication with an optoelectronic transducer;
an electro-optic transducer driver configured for communication with an electro-optic transducer; and
a control module configured to control the operation of the electro-optic transducer driver and the post-amplifier;
wherein the post-amplifier, the electro-optic transducer driver, and the control module are integrated together in a single integrated circuit (IC) without the use of a printed circuit board (PCB) in interconnecting the post-amplifier, the electro-optic transducer driver, and the control module.
