FIELD: aviation.
SUBSTANCE: invention can be used for power supply from ground power supply of onboard electric equipment of tethered unmanned aerial vehicles of long operation. Device for power supply comprises located on ground facility source of electric power, ground converter, cable-rope, intended for electric power transmission from ground converter to aircraft, and onboard converter arranged on aircraft, charging-switching device and backup storage battery intended for power supply of aircraft onboard equipment. Onboard converter is implemented in the form of non-isolated multiphase DC voltage converter with digital stabilization of output voltage by feedback signals, formed by measuring current and voltage sensors located at the output of the multiphase converter, and inclusion of a battery charging unit into the onboard converter.
EFFECT: higher accuracy of maintaining output voltage in static and dynamic modes of operation.
