Embodiment

The high-voltage energy storage capacitor C that is composed in series by electrochemical capacitor meets high voltage pulse output winding L ₃Rectification output end, high pressure detect and the photoelectricity coupling circuit in neon bulb LH in parallel with high-voltage energy storage capacitor, the controllable silicon SCR in the photodiode VD connection control circuit is controlled the utmost point.Controllable silicon SCR in the control circuit, triode T ₁, T ₂, T ₃Reach ic chip and be connected in the electric power loop, at anode and the T of SCR ₁Base stage between be in series with diode D ₁, D ₂, T ₁Colelctor electrode meet T ₂Base stage, T ₂Colelctor electrode be connected 3 pin and the T of IC with 2,6 pin of ic chip ₃The connecting line of base stage on LED is arranged ₂Triode T in the oscillating circuit ₄Base stage meets T ₃Colelctor electrode, colelctor electrode meets the low-voltage coil L of stepup transformer ₂The lower end.

When circuit was started working, photodiode VD was ∞ because of unglazed according to resistance, and controllable silicon SCR is ended T because of the triggerless electric current ₁Conducting, T ₂End, 2,6 pin of IC are high potential, 3 pin are electronegative potential, T ₃End, the oscillation step-up circuit operate as normal is by L ₃The high voltage pulse that induction produces is through D ₃, D ₄Charge D when minimum output voltage when being charged to mousetrap such as 1300V after the rectification at stand-by state to high-voltage energy storage capacitor C ₅Be reversed and puncture and conducting (because R ₁₁Metering function, a little less than breakdown current is atomic, D ₅Can not damage), neon bulb LH is lighted.The photodiode VD that abuts against with LH reduces because of illumination resistance is arranged, the SCR conducting that is triggered, T ₁Base stage become electronegative potential, T ₁End, power supply is through R ₅To C ₃Charging.At this moment T ₂Base stage still be electronegative potential, T ₂End, 2,6 pin of IC are electronegative potential for high potential, 3 pin still, T ₃End, oscillating circuit is operate as normal still, continues to charge to high-voltage energy storage capacitor C.After about 50 seconds, C ₃Cathode voltage is increased to 0.6V, T ₂Conducting, 2,6 pin of IC become electronegative potential, 3 pin become high potential, T ₃Saturation conduction, T ₄Base stage by shorted to earth, the oscillating circuit failure of oscillation, at this moment C has been charged to about the ceiling voltage such as 1800V of high-voltage output end.While LED ₂Bright, the expression control circuit starts to control, and oscillating circuit is not worked.Afterwards, when the voltage of C drops to 1300V gradually, D ₅End, LH extinguishes, and VD is ∞ because of its resistance of unglazed photograph, and SCR ends, T ₁Conducting, C ₃Through T ₁Discharge, T ₂, T ₃All end, oscillating circuit is resumed work, and so goes round and begins again, and the voltage of high-voltage output end is remained between 1300V～1800V.R ₉, R ₁₀Be high pressure output current limiting resistance, be used to prevent that output from being damaged high-voltage energy storage capacitor C by short circuit.T ₅And DW ₂Form a mu balanced circuit, when high-voltage output end has load and externally discharges, at T ₅Collector and emitter between produce the 9.6V pressure drop, be T ₆, composition such as HTD buzzer alarm circuit the warning of ringing of the operating voltage of nearly 10V, HTD is provided.LED ₁Be the double supply voltage indication of work indication.

When supply voltage is 6V, the about 0.6A of mousetrap operating current, when voltage pulse output reached peak, control circuit started to control, the oscillating circuit failure of oscillation, at this moment the complete machine electric current is less than 25mA.High pressure drops to 1300V after half an hour approximately, and oscillating circuit is resumed work, and after about 50 seconds, high pressure rises to 1800V again, goes round and begins again.Thereby under unloaded (promptly waiting for) state, oscillating circuit is in the discontinuous operation state, and average mutual capacitance is very little, and power consumption is economic, No. 1 battery of four joints can continuous operation a couple of days.Because this machine mainly utilizes the electric energy of high-voltage energy storage capacitor accumulation to discharge at short notice hits unconsciously and be caught mouse, output voltage can be dropped rapidly to several hectovolts in the several seconds, can not work the mischief to people and animals, and is quite safe.This machine can be applicable to electric fence etc.
