Abstract
The utility model discloses a wireless power supply device which comprises a transmitting end and a receiving end, wherein the transmitting end and the receiving end are connected by a magnetic coupling device; the transmitting end is composed of a primary coil and a control circuit, wherein a primary magnetic core is arranged in the primary coil; the control circuit comprises a direct-current power supply and a controller connected with the direct-current power supply by a driver; the controller is connected with the primary coil by the driver to control the primary coil; and the receiving end is composed of a rectifier filter, a DC(Direct Current)-DC converter and a secondary coil in which a second magnetic core is arranged, wherein the secondary coil is connected with a load successively by the rectifier filter and the DC-DC converter to supply power for the load. The wireless power supply device has the beneficial effect that the electricity energy is transmitted to the load wirelessly by the electromagnetic field sensing principle without any physical connection, which is convenient and safe.
Description
Technical field
The utility model relates to a kind of electric supply installation in the power supply field, particularly a kind of wireless power supply.
Background technology
Need a charger during usually to the battery charge of mobile devices such as mobile phone, notebook, an end is connected on the mains supply, and an other end is connected on the mobile device; Inconvenience is not only used in frequent plug, and damages easily, and is simultaneously also dangerous; And its; In the occasion of work under bad environment, in water, should avoid electric contact as far as possible.Need generally adopt battery to the circuit supplies such as transducer in the closed container, yet the useful life of battery is limited after all, when electric weight exhausted, it was the thing that bothers very much that closed container is opened the replacing battery, and some occasion also is unallowed.
The utility model content
To the defective of existing electric supply installation, the utility model provides a kind of wireless power supply.
To achieve these goals, the measure taked of the utility model is:
A kind of wireless power supply; Comprise transmitting terminal and receiving terminal, transmitting terminal is connected through magnetic coupler with receiving terminal, and transmitting terminal is made up of primary coil and control circuit that inside is provided with former magnetic core; Control circuit comprises DC power supply and the controller that links to each other with DC power supply through driver; Controller links to each other with primary coil through driver, realizes the control to primary coil, and receiving terminal is made up of rectifier filter, DC-DC transducer and the inner secondary coil that is provided with secondary magnetic core; Secondary coil links to each other with load through rectifier filter, DC-DC transducer successively, realizes electric;
The both sides of said former magnetic core and secondary magnetic core are provided with a breach.
The beneficial effect of the utility model: need not any connection physically,, electric energy is transferred to load with wireless mode, convenient, safety through the electromagnetic field inducing principle.
Description of drawings
The functional-block diagram of Fig. 1, the utility model;
The vertical view of Fig. 2, the utility model magnetic core.
Embodiment
A kind of wireless power supply; Comprise transmitting terminal and receiving terminal, transmitting terminal is connected through magnetic coupler with receiving terminal, and transmitting terminal is made up of primary coil and control circuit that inside is provided with former magnetic core; Control circuit comprises DC power supply and the controller that links to each other with DC power supply through driver; Controller links to each other with primary coil through driver, realizes the control to primary coil, and receiving terminal is made up of rectifier filter, DC-DC transducer and the inner secondary coil that is provided with secondary magnetic core; Secondary coil links to each other with load through rectifier filter, DC-DC transducer successively, realizes electric; The both sides of said former magnetic core and secondary magnetic core are provided with a very little breach, and breach is that for preventing leakage field, breach should be enough little for the convenience of winding wire lead-in wire.
The inner ring outer ring of primary coil and secondary coil needs enough greatly, the coupling efficiency when helping increasing primary coil and secondary coil central axis like this and misfitting.Because transmitting terminal is connected through magnetic coupler with receiving terminal, so primary coil and secondary coil are separable two individuals.
The operation principle of the utility model: be sent to load to the energy of power supply output through alternating magnetic field.When needs were supplied power, near transmitting coil, through electromagnetic induction, the energy of transmitting terminal promptly was transferred to receiving terminal with the receiving coil of load.
The beneficial effect of the utility model: need not any connection physically,, electric energy is transferred to load with wireless mode, convenient, safety through the electromagnetic field inducing principle.
Those skilled in the art's simple change and replacement all are within the protection range of the utility model in this area.
