FIELD: electricity. ^ SUBSTANCE: optical system of power supply, comprising a single photovoltaic element, which generates the first voltage as light drops on it; besides, the single photovoltaic element is a single diode; a voltage amplifier, connected with the photovoltaic element, which receives the first voltage from the photovoltaic element and generates the second voltage, which is higher than the first voltage, besides, the voltage amplifier is supplied only by the first voltage from the photovoltaic element, at the same time the first voltage is more than 1 volt. Also a system of a sensor is proposed, comprising a single photovoltaic element and a method of optical power supply to an electric circuit. ^ EFFECT: possibility to create a system of power supply, which has advantages of an optical power supply device and is efficient in cost. ^ 25 cl, 3 dwg |
