Abstract
The invention discloses a transceiver based on T5336 and a C-class amplification circuit. The transceiver comprises an emitter and a receiver which are formed by T5336 series of integrated circuits. The emitter has the function of automatically controlling electromagnetic wave emission voltage and frequency of a transmitting coil; the 7 and 8 output port voltages of the T5336 are output to a parallel resonance circuit formed by coils and capacitors through the C-class amplification circuit formed by a triode 13003 and a peripheral circuit thereof so as to compensate the lost voltage of impedance and energy transfer in the circuit, and enable the emission electromagnetic wave of the transmitting coil to change according to the sinusoidal waveform; electric energy emitted from the emitter is transmitted to the receiver through electro-magnetic induction between the coils; and induced current of a coil of the receiver is converted into a DC current through a full-bridge rectifier. The transceiver can enable smart mobile phones and embedded devices to be charged wirelessly, is convenient to carry, helps to solve the problems of interface wearing and loosening caused by conventional wired charging, and improves charging efficiency; charging can be carried out directly under the condition that a cell fails to be taken out; and in the wireless charging process, the device can still work normally.
Description
Technical field
The present invention relates to charging device, particularly based on the transceiver of T5336 and Class C amplifying circuit.
Background technology
At present, its charging modes of portable electric appts such as mobile phone, music/video player and notebook computer are traditional charging modes that one end is connected AC power and the other end and connects portable electric appts rechargeable battery, this mode has a lot of disadvantageous place, and plug is easy to damage joint first frequently. also may make human electric shock in addition.Therefore, the demand of user to radio source system convenience and fail safe increases just fast.The portable equipments such as smart mobile phone, music/video player, camera and game console just wherein several battery-powered products that can be upgraded to radio source system.Although near field inductive power supply coupling technique occurs already, its range of application is only confined to an extremely low power level.Because current mobile device needs increasing electric energy, and high power consumption battery needs more advanced control system.
Summary of the invention
The object of the present invention is to provide a kind of transceiver based on T5336 and Class C amplifying circuit, smart mobile phone and embedded device can be made to carry out wireless charging, easy to carry, eliminate traditional wire charge the interface wearing and tearing and loosening problem that bring, improve charge efficiency, under the state that battery is not removed, directly carry out charging work, in the process of wireless charging, equipment still normally works.
The object of the present invention is achieved like this: a kind of transceiver based on T5336 and Class C amplifying circuit, comprise the reflector and receiver that are made up of T5336 series integrated circuit, the electromagnetism bag emitting voltage of the automatic control transmitting coil that reflector has and frequency, the delivery outlet voltage of reflector T5336 exports through the Class C amplifying circuit of triode and peripheral circuit composition thereof the shunt-resonant circuit that coil and electric capacity forms to, in order to the voltage of compensating circuit middle impedance and energy transfer losses, the emitting electromagnetic wave of transmitting coil is changed according to sinusoidal waveform; The electric flux launched from reflector is transferred to receiver by the electromagnetic induction between coil, the induced current of the coil that receiver has by full-bridge rectifier so that become direct current.
Electric energy is wirelessly transferred to battery by coil by the present invention, and transmitter and receiver all comprise coil, and electric energy can transmitted in both directions between, and can not because inductively producing electrical contact.Because electric energy is transferred to receiver by coil-induced from transmitter, therefore, transmitter must provide electric energy for coil by the frequency of utilization switching current that is enough to optimize coupling between coil, subsequently, receiver coil just can receive near field induction electric energy, and uses rectifier and voltage regulator circuit to export direct current.Control power delivery, receiver must carry out continuous communiction with transmitter, to indicate when required power, and the watt level that send and when stop transmitted power.The present invention carrys out exchange communication data by the identical coil of coupling power.The present invention can make smart mobile phone and embedded device carry out wireless charging, easy to carry, eliminate traditional wire charge the interface wearing and tearing and loosening problem that bring, improve charge efficiency, directly charging work is carried out under the state that battery is not removed, in the process of wireless charging, equipment still normally works.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the circuit connection structure schematic diagram of reflector of the present invention;
Fig. 2 is the circuit connection structure schematic diagram of receiver of the present invention.
Embodiment
A kind of transceiver based on T5336 and Class C amplifying circuit, comprise the reflector and receiver that are made up of T5336 series integrated circuit, the electromagnetism bag emitting voltage of the automatic control transmitting coil that reflector has and frequency, 7, No. 8 delivery outlet voltages of reflector T5336 export through the Class C amplifying circuit of triode 13003 and peripheral circuit composition thereof the shunt-resonant circuit that coil and electric capacity forms to, in order to the voltage of compensating circuit middle impedance and energy transfer losses, the emitting electromagnetic wave of transmitting coil is changed according to sinusoidal waveform; The electric flux launched from reflector is transferred to receiver by the electromagnetic induction between coil, the induced current of the coil that receiver has by full-bridge rectifier so that become direct current.
As shown in Figure 1, T5336 series integrated circuit, employing be CMOS manufacture craft, be specifically designed in intelligent wireless charging, automatically control electromagnetism bag emitting voltage and the frequency of transmitting coil.Can not ignore due to the internal resistance of coil in LC oscillating circuit earthquake process and cause oscillating current in circuit to be certain to significantly decay in the energy loss of energy transport, at this moment 7, No. 8 delivery outlet voltages of control T5336, the shunt-resonant circuit that coil and electric capacity form is exported to after the Class C amplifying circuit of triode 13003 and peripheral circuit composition thereof, the voltage at adjustment two ends, in order to the voltage of compensating circuit middle impedance and energy transfer losses, the emitting electromagnetic wave of transmitting coil is made to maintain simple alternating current change.
As shown in Figure 2, pass through the electromagnetic induction between coil from the electric flux of reflector transmitting, be transferred to receiver.The induced current of receiver coil becomes direct current by full-bridge rectifier, charges to mobile phone.C9, C10 are filter capacitors, are filtered by most of alternating current that rectification circuit exports, thus obtain smoother direct current.In small-power rectification circuit, often practical is capacitor filtering.
It is little that the present invention has volume, and charging current is large, slight fever, the technological merits such as not misoperation.The present invention is anti-interference, even if electromagnet, metal etc. are placed on expelling plate of the present invention, the present invention still can normally work.The present invention has perfect transmitting, receives fault self-checking function.The present invention can be used in different wireless chargers.
