High-frequency inversion topology in non-contact charger systems typically has full-bridge inverting topology, slab bridge inversion topological, push-pull type inversion topological etc..Full-bridge inverting topological sum semi-bridge inversion topology is required for isolating the circuit such as light source, optocoupler.This not only increases the volume of system, and improves the cost of charging system, is not suitable in charging system using.And push-pull type inversion topological may be designed as from shaking inversion, it is only necessary to adding a small amount of auxiliary element in main circuit can realize the driving of switching device, and its volume and cost are smaller.Therefore, according to the feature of portable charging apparatus, select push-pull type inversion topological as the inversion topological of native system.

Push-pull type inversion topological can realize circuit and certainly shake work, thus avoids at switching tube Q1、Q2Two ends add on-off control drive circuit.The gate drive voltage of switching tube directly obtains from switching tube two ends, and drive circuit is made up of a Zener diode and a load in series.Direct voltage source and DC inductance L2The DC current source of composition equivalence.L3、L4For dividing the equivalent inductance of two windings of transformator mutually.L1For transmitting coil equivalent inductance, C is that transmitting coil compensates electric capacity C.Selecting voltage stabilizing value is the Zener diode of 5V, and driving voltage is the switching tube of 5V.
During stable state, circuit has two operation modes, and its work process is as follows:
Mode I
As shown in Figure 3, during mode I, compensate on the voltage at electric capacity C two ends just lower negative, i.e. high B point position, A point position is low.When A point voltage is higher than 5V, stabilivolt D2Voltage be 5V, drive Q2Conducting.Now the current direction of circuit is as shown in thick line in accompanying drawing 3, and DC current is through dividing transformator atmosphere I mutually1、I2(both are of substantially equal), wherein I1Resonant tank is entered, at B point and I by A point2Converge, through Q2, so push-pull type topology flows into the half that electric current is equivalent current source of resonant tank, with compensation condenser type half-bridge topology antithesis, I1By A point to resonant tank Implantation Energy, to compensating electric capacity C charging, the current potential of A point presses the change of half-sinusoid rule.When A point current potential deteriorates to less than 5V, Q2Turn off, reversely increase after compensating the voltage zero-cross at electric capacity C two ends.
Mode II
As shown in Figure 4, during mode II, compensate the voltage upset at electric capacity C two ends, lower just upper negative, i.e. high A point position, B point position.When B point voltage is more than 5V, stabilivolt D1Voltage be 5V, drive Q1Conducting.Now the current direction of circuit is as shown in thick line in accompanying drawing 4, I2It is resonant tank inverse injection energy by B point, and at A point and I1Converge, through Q1Flow back to DC source.Now A point current potential is zero, and B point current potential is higher than 5V and presses the change of half-sinusoid rule.When B point current potential deteriorates to less than Q1Time, Q1Turning off, after compensating the voltage zero-cross at electric capacity C two ends, forward increases.
Being again introduced into mode I when compensating electric capacity C voltage forward more than 5V, circuit cycles is operated in two above mode, at transmitting coil L1Middle generation sinusoidal current.
The control method of circuit is simple, it is not necessary to the drive circuit of extra switch pipe, it is achieved that circuit certainly shake inversion.Additionally, the switching of switching tube on off state is when compensation 2 electric potential differences of electric capacity C are about 5V, substantially achieves ZVS, thus reduce the loss of whole circuit.
Work process of the present utility model is:
The first step: when in air, coal gas density reaches rated value, and coal gas induction apparatus 11 signal output part part brings into operation, continues output signal；
Second step: wireless power controls to be partially received Guan Bi switch after lasting signal, (wireless power supply system mainly uses electromagnetic induction principle to the wireless power supply system that brings into operation, and carries out energy coupling by coil and realizes the transmission of energy.During system work, electric main is transformed into unidirectional current through full bridge rectifier 23 by input, and after power management module, the unidirectional current of output is converted into high-frequency alternating current supply armature winding 25 by full-bridge inverting.By 2 coil coupled transfer energy, the electric current of secondary coil output is exhaust system 30(such as exhaust fan 32 through accepting change-over circuit) power supply.The magnetic field of change can produce the electric field of change, the electric field of change can produce the magnetic field of change, its size all rates of change with them have relation, and the rate of change of SIN function is another one SIN function, so electromagnetic wave can blaze abroad, and the generation of induced voltage is relevant to the change of magnetic flux, so the magnetic field of coil inside change produces induced voltage, thus complete power supply process)；
3rd step: when indoor gas concentration drops to another safety value, and coal gas induction apparatus 11 signal output part part is out of service, i.e. stops output signal, and wireless power partial switch disconnects, and exhaust system 30 is automatically stopped work.
