Abstract

This invention belongs to the technical field of the power source and is a wireless power source apparatus. The power source available currently requires power source lines connected to the power source transformer, so it is not convenient if an equipment using electricity is in a moving status; if a battery were used, the equipment would be not able to run because the energy of the battery would be consumed up. Now these problems are solved. Said wireless power source comprises a power source transmitter and a power source receiver. Said power source transmitter has a transmitting coil wound on a magnet conductor and a oscillation circuit of high frequency connected to the transmitting coil; said power source receiver is a receiving coil wound on a magnet conductor.

Description

Wireless power device
Technical field
The invention belongs to power technique fields, is a wireless power device.
Background technology
Existing power supply mainly contains by the AC power of power transformer output and passes through battery or the DC power supply of storage battery output, when power consumption equipment uses power supply at needs, as use alternating current, needing a power line links to each other with power transformer, since the restriction of power line, very inconvenience when power consumption equipment is in mobile status.And when using battery, because the energy storage of battery is limited, in use for some time, power supply energy can be depleted, causes power consumption equipment to work.
Summary of the invention
The object of the present invention is to provide one not need power line to connect the wireless power device that just can realize power delivery.
For realizing purpose of the present invention, described wireless power device comprises power supply reflector and power supply receiver, and described power supply reflector has the transmitting coil that is wound on the magnetic conductor, the high-frequency oscillating circuits that is connected with transmitting coil; Described power supply receiver is the receiving coil that is wound on the magnetic conductor.
Owing to adopted power supply reflector and power supply receiver, can convert direct current energy or alternating current energy line to direct voltage, be transformed into high frequency electric source voltage through high-frequency oscillating circuits, be added on the transmitting coil in the power supply reflector, launch by magnetic conductor, sense the high frequency electric source signal by the magnetic conductor in the power supply receiver again, by receiving coil output, thus the wireless transmission of realization power supply.
