The unmanned aerial vehicle (UAV) industry is witnessing unprecedented growth, transitioning rapidly from simple recreational flight platforms to highly sophisticated commercial, industrial, and military systems. Modern UAV applications demand continuous, high-performance operation in challenging environments. Whether it is a tethered drone designed for 24/7 surveillance, a rapid-charging base station for autonomous inspection, or a high-precision hardware-in-the-loop (HIL) testing facility, the backbone of these operations is a robust and reliable AC Power Supply for UAV Power Systems.
Converting local AC power grids or portable generators into highly regulated, low-noise DC power lines to sustain extended flight cycles.
Overcoming the electrical resistance of long tether cables by stepping up AC-DC output to high voltage ranges (up to 400V or 800V).
Engineered to handle extreme outdoor temperatures, maintaining optimal efficiency and preventing thermal runaway during field setups.
Historically, UAVs relied solely on onboard lithium-polymer (LiPo) batteries, which restricted flight times to roughly 20 to 40 minutes. In commercial sectors such as industrial inspection, border patrol, telecommunications broadcasting, and military reconnaissance, this short duration presents a severe operational bottleneck. To address this, system integrators are increasingly adopting tethered drone systems. By linking the drone to a ground station via a thin, lightweight cable, electrical energy can be transmitted continuously from the ground to the air.
This ground-based power station relies heavily on specialized AC to DC switching power supplies. The primary challenge here is efficiency and weight. The power supply must convert standard AC mains (single-phase 110V/220V or three-phase 380V) into a high-voltage DC bus. This high voltage is transmitted up the tether to minimize current, thereby allowing the use of thinner, lighter copper or copper-clad aluminum wires. Once the power reaches the UAV, an onboard DC-DC converter steps it down to the appropriate voltage for the ESCs (Electronic Speed Controllers) and flight avionics. Consequently, a stable, low-ripple, and highly efficient AC power supply is critical to keeping the drone airborne indefinitely.

Established in 2011, Huyssen power is committed to being a better provider of power solutions. Our production lines include AC-DC power supplies, Din Rail power supply, Programmable power supply, Battery chargers, DC DC converters, etc. We design and manufacture high-reliability power systems that seamlessly integrate with modern drone ground stations and aerospace testing platforms.
LEARN MORETethered drones are widely deployed for long-duration security monitoring, border control, and live event broadcasting. In these scenarios, the ground power unit (GPU) houses a high-power AC-DC switching power supply (typically ranging from 2kW to 8kW, such as our 8000W adjustable models). The power supply converts local AC grid power or generator output into a high-voltage DC line (often 300V to 400V DC). This high-voltage power travels through the tether cable to the drone, ensuring that the current remains low, which minimizes the heat generated in the tether and prevents the cable from becoming too heavy to lift. A failure in the AC power supply would result in an immediate loss of power to the drone, making reliability and safety protections (such as over-voltage, over-current, and over-temperature protections) paramount.
Ground Control Stations serve as the command center for drone operations, containing telemetry receivers, monitors, flight control hardware, and communication antennas. These electronic components require clean, stable, and noise-free power to prevent interference with sensitive RF signals. DIN rail switching power supplies (like the NDR-240-48 or NDR-120-24) are commonly mounted inside GCS racks to provide reliable power. Their compact design, high efficiency, and DIN rail mounting capability make them ideal for integration into mobile vehicle-mounted command centers where space is limited and vibration resistance is critical.
For operations utilizing untethered drones, rapid battery charging is crucial to maintaining high operational readiness. Industrial UAV charging stations require high-power AC-DC converters to charge heavy-duty smart flight batteries quickly and safely. High-power programmable power supplies allow operators to adjust the output voltage and current profiles dynamically to match the specific charging requirements of different battery packs (such as 12S or 14S LiPo batteries), maximizing battery lifespan while minimizing downtime.
During the design and testing phases of UAV development, engineers use programmable power supplies to simulate various battery conditions, such as voltage drops, transients, and discharge curves. This allows the flight control software and hardware to be tested under realistic electrical conditions without risking an actual drone flight. A programmable power supply capable of precise digital adjustment (like the 8000W 0-200V 40A DC Programmable Power Supply) is indispensable in these testing environments, enabling automated testing procedures via computer control interfaces.
We know well that only by constantly innovating can we maintain a leading position in the fierce market competition. Therefore, we launch 2-3 new models of power supplies every month.
