Scientists at Novosibirsk State Technical University (NSTU) have developed a method for powering wired unmanned aerial vehicles, which significantly increases their continuous operation time. The solution was proposed by university specialists, based on the use of a voltage converter with an intermediate high-voltage DC line.
The development aims to eliminate the key limitation of battery-powered drones – limited energy reserves, which reduces their effectiveness in long-term tasks. The new scheme involves supplying power via cable from a ground source with control over electrical energy parameters.
The university clarified that the technology is based on wide-bandgap semiconductor devices, resonant circuit solutions, and planar transformers. This approach allows for reducing the mass and dimensions of the conversion equipment, which is critical for unmanned systems.
UAV manufacturers are named as the target consumers of the technology. The company "Aerofregat" acts as a qualified customer and plans to participate in flight tests of prototypes scheduled for late 2027.
