Control circuit passes through singlechip + UCC3895 and detects load nature and type, has realized the control to inverter circuit to realize the self -adaptive control of frequency, further satisfy various different frequencies and charge or supply power the needs of load.
Description
Technical field
This utility model belongs to a kind of wireless power field, relates to resonance manner wireless power transmission technology, is specifically related to a kind of frequency adaptive wireless and powers desktop.
Background technology
Development and the change of people's idea along with science and technology, desktop people succinct, attractive in appearance, safe increasingly pay close attention to, prior art has been realized in using the desktop charging of wireless power mode and power supply, but frequency regulation can not be realized, but the fixing mode of resonance used, can not the needs of compatible various load frequency standards, Practical Performance is poor.Therefore design a wireless power desktop being adapted to different frequency and become the urgent needs of present people.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, it is proposed that a kind of simple in construction and be capable of frequency adaptive wireless power desktop, meets charging or the power demands of different frequency load.
For realizing the purpose of this utility model, this utility model provides the desktop of a kind of wireless power, its improvement: this device includes that power supply, power supply are divided into main power source and accessory power supply two parts, and main power source is main circuit power supply, and accessory power supply is that control circuit is powered；The frequency of characteristic frequency in circuit or the frequency beyond this frequency are effectively filtered out by filter circuit, obtain the power supply signal of a characteristic frequency；Main circuit current is converted into the High Level AC Voltage of high frequency by inverter circuit；Transtation mission circuit, is converted into high frequency alternating current electromagnetic wave and launches；Receive circuit, be the electromagnetic wave receiving transtation mission circuit；Rectification circuit, be coupled to receive circuit induction electromotive force, be converted to alternating current powering load or charging after rectifying and wave-filtering voltage stabilizing.
Also including that control circuit uses and realize the control to inverter circuit by single-chip microcomputer+UCC3895, single-chip microcomputer is responsible for detecting load characteristic and type, identifies the frequency required for load, thus carry out the Automatic adjusument of frequency after shifting to control；Drive circuit, feeds back to main circuit after receiving the required frequency of load；Inverter circuit, uses full-bridge topologies to provide high frequency electric source for transtation mission circuit；
Described transtation mission circuit is consistent with the resonant frequency receiving circuit.
Load characteristic is distinguished by described transmitting terminal control circuit by chip microcontroller, then realizes system frequency Automatic adjusument, to meet the load end requirement to characteristic frequency by the frequency of regulation transmitting terminal.
Described desktop wireless can realize charging or the power supply of plurality of devices, such as wireless desk lamp, radio fan, wireless charger etc..
This utility model not only solves when wired desktop is powered unsightly, dangerous and mobile inconvenient problem, control circuit is by single-chip microcomputer+UCC3895 detection load characteristic and type simultaneously, achieve the control to inverter circuit, thus realize the Automatic adjusument of frequency, meet the charging of various different frequency or the needs for electric loading further, it is easier to marketing.
Accompanying drawing explanation
Fig. 1 is that frequency adaptive wireless is powered desktop circuit overall block diagram, and dotted line frame is main circuit；Remainder is auxiliary circuit；
Fig. 2 is inverter major loop topological structure.
Sequence number illustrates: 1. main power source 2. filter circuit 3. inverter circuit 4. transtation mission circuit 5. receives circuit 6. rectification circuit 7. accessory power supply 8. control circuit 9. drive circuit 10. and loads.
Detailed description of the invention
Referring to the drawings technical solution of the present invention is further described.
The present invention includes a conventional wireless power desktop, and with reference to Fig. 1, apparatus of the present invention include main power source 1, filter circuit 2, inverter circuit 3, transtation mission circuit 4, receive circuit 5, rectification circuit 6, accessory power supply 7, control circuit 8, drive circuit 9.After switching on power, main power source 1 is powered to main circuit, accessory power supply 7 powers to control circuit 8, required power supply or the load 10 of charging, sampled feed back to control circuit 8, control circuit 8 uses single-chip microcomputer+UCC3895 detection load characteristic and type, carry out the Automatic adjusument of frequency, and identify the frequency required for load, drive circuit 9 is passed to through shifting to control, feed back to main circuit the most again, such as Fig. 2 inverter circuit 3, full-bridge topologies is used to provide high frequency electric source for transtation mission circuit 4, transtation mission circuit 4, high frequency alternating current is converted into electromagnetic wave and launches, receive circuit 5 receive the electromagnetic wave of transtation mission circuit and pass to rectification circuit 6, rectification circuit 6 be coupled to receive circuit induction electromotive force, be converted to exchange after rectifying and wave-filtering voltage stabilizing supply electricity to load 10 power supplies or charging.
The technical solution of the utility model is not restricted in the range of embodiment described in the utility model, and the technology contents of the most detailed description of this utility model is known technology.
