Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
The inductive coupling type charging is adopted in the charging of the chargeable remote controller of the utility model, its theory diagram as shown in Figure 1, the power supply of electrical equipment is connected with current rectifying and wave filtering circuit, AC/AC inverter circuit, induction coupling successively, induction coupling is connected with current rectifying and wave filtering circuit, remote controller storage battery successively, gives the remote controller charge in batteries.Adopt cable to be connected between AC/AC inverter circuit and the induction coupling.
The primary coil of induction coupling is arranged on electrical equipment inside, and the secondary coil of induction coupling is arranged on remote controller inside.
If the power unit of electrical equipment does not have electromagnetic interface filter, add electromagnetic interface filter.
Induction coupling charging remote controller is operated under the high frequency state, and the harmonic wave of generation can pollute electrical network, so will take effective measures, just imitates and technology such as reactive power compensation as power factor, can add PFC.Consider cost, it is also passable not add PFC.
The effect of AC/AC inversion is to produce higher frequency, reduces the induction coupling volume.
The size of transmission cable is main relevant with transmission current.Therefore reduce the size that charging current can reduce cable accordingly,, can adopt coaxial cable between AC/AC inverter circuit and the induction coupling in order to make the power consumption minimum of cable.
The primary coil of induction coupling and the turn ratio between the secondary coil adopted 1: 1.
The AC/DC rectification can be adopted unidirectional bridge rectifier, also can adopt the rectification circuit of other form.
The storage battery of remote controller adopts the rechargeable battery of clean environment firendly.
With a specific embodiment the utility model is further specified below.Fig. 2 is the specific embodiment circuit diagram of chargeable remote controller of the utility model and electrical equipment, and the full bridge rectifier of being made up of D1, D2, D3, D4 is adopted in power supply output rectification, and the capacitor filtering of being made up of C1, C2 is adopted in power supply output filtering.For the capacitive filtering link, charger is the high-frequency current characteristic, and the current source type circuit is less to the sensitivity that the charger operating frequency changes and power grade changes, and the circuit of secondary employing capacitive filtering, and the secondary diode need not adopt the over-voltage clamping measure.
Behind the rectifying and wave-filtering, by S, D
SFinish the AC/AC inversion, the main effect of inversion is exactly the operating frequency that improves induction coupling, makes its high frequencyization, reduces the volume of induction coupling.
Frequency has improved, but along with the improving constantly of frequency, adopts the induction coupling of hard switching mode, and its switching loss will increase greatly, reduce the operating efficiency of variator.So in order to realize the charging of high-frequency, high power grade, soft switch is absolutely necessary.

2During conducting, store energy is in cut-off state with power supply output rectifying tube in the input filter inductance.When any one was in cut-off state in the switching tube, storage power was transferred to secondary by former limit winding.Variator is symmetry work, and magnetic flux can reset.
By induction coupling, again through the full-bridge rectification formed by D5, D6, D7, D8 and the filtering of C3, just can be to the charge in batteries of remote controller.
The structural representation of chargeable remote controller of the utility model and electrical equipment for the ease of the identification induction zone, indicates induction zone at the casing external Design mark 2 of electrical equipment 1 as shown in Figure 3.When the remote controller electric weight was not enough, the induction zone charging that remote controller 3 is put into mark got final product.
Electrical equipment of the present utility model can be the electrical equipment that TV, air-conditioning, DVD etc. have remote controller.
Although relate to a kind of chargeable remote controller and electrical equipment has carried out special description to disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
