In most deterrent devices to protect against wild birds the principle of electric shock is applied, which can adversely affect the health of living beings, namely, cardiovascular system. The longer the passage of electric current through the body, the greater the probability of coincidence of the time of passage of current through the heart by the coinci-dent phase of the cardio cycle. Such devices, as a rule, use high voltage of low frequency. The use of high-frequency voltage is safer for birds and the man. It has thermal selective effect in the areas of contact between high-voltage electrodes and living tissues. The change in pulse porosity parameter in the direction of reducing the pulse width reduces killing effect of high voltage. At the core of the technique for applying high-frequency voltage all these principles lie. Using this knowledge the de-vice named ‘High-voltage umbrella’ powered by a rechargeable battery was designed. Received ten-sion will be transformed in high-voltage by means of the transformer with the ferrite core allowing us-ing the frequency with higher parameter. Resulting voltage is converted to high voltage using the trans-former with a ferrite core, which allows using the frequency with a higher parameter. The design of the additives and high-voltage elements on them allow a bird of any size to use this device as a ful-crum of without hesitation. The sensor system con-trols the approach of the bird and direct contact with the electrodes to activate the pulse discharge. At the same time the plant remains passive when it comes to human contact due to to the information from capacitive sensors.
