Description

Automatically the capacitor of control capacittance amount

Technical field

The present invention relates to the capacitor in the electronic device, is a kind of automatically capacitor of control capacittance amount concretely.

Background technology

At present, adjustable condenser can play the fine setting effect to the filtering in the circuit or coupling circuit, in order to reach the high accuracy effect of circuit, but, when the change of load current, the capacity of capacitor but can not change according to the change of load current, causes or ripple current is less than normal to set off an explosion, impedance is excessive, causes circuit combination distortion.

Summary of the invention

The object of the present invention is to provide a kind of automatically capacitor of control capacittance amount, have according to the change of load current and frequency and the function of regulating capacitor capacity voluntarily.

The present invention realizes with following technical scheme: a kind of automatically capacitor of control capacittance amount, its structure is comprised of main body, capacitance, a slide-bar, No. two slide-bars, contact block, inductor, adjusting terminal, positive terminal, negative terminal, resistors.It is characterized in that, the inside of main body is equipped with capacitance, slide-bar, No. two slide-bars, contact block, inductor, the side of contact block contacts with the positive pole-face of capacitance, the back side of contact block is connected with the number of being connected slide-bar with a slide-bar, and inductor one end is connected with contact block, and the other end is connected with No. two slide-bars, and draw a positive terminal, the negative pole end of capacitance is drawn a negative terminal, and slide-bar and adjustable side sub-connection are regulated terminal by resistor and earth loop.Positive terminal is connected with positive source, negative terminal is connected with power cathode, when the inductor inductive load current is low, the inductance type of a slide-bar and No. two slide-bars also reduces synchronously, contact block descends synchronously along a slide-bar and No. two slide-bars, positive terminal is through No. two slide-bars, the volume of contact block and capacitance descends, when load current increases, the inductance type of a slide-bar and No. two slide-bars also raises synchronously, contact block rises synchronously along a slide-bar and No. two slide-bars, positive terminal is through No. two slide-bars, the volume of contact block and capacitance rises, and has realized according to the variation of load current and frequency and the function that the capacity of capacitor also changes thereupon.

Load current fluctuation is large, is below the 1K Ω regulating the resistor that is connected in series between terminal and the ground wire, and the load current fluctuation is little, is more than the 1K Ω regulating the resistor that is connected in series between terminal and the ground wire.

When load is 12V35W, and ambient voltage at 12V between the 15V, power becomes large with the rising of voltage, then the resistance of resistor is 500 Ω, the every rising 1V of voltage, the inductance type of a slide-bar and No. two slide-bars touch and make contact block rising 1mm, and capacitance promotes 10UF.

When load is control module, and frequency at 10Hz between the 200Hz, then the resistance of resistor is 10K Ω, the every rising 10Hz of frequency, the inductance type of a slide-bar and No. two slide-bars touch and to make contact block rising 0.1mm, capacitance promotes 0.001UF.

Beneficial effect is that originally the capacitor of control capacittance amount has the variation that realizes according to load current and frequency, the voluntarily function of the capacity of regulating capacitor automatically.
