View DetailsIn modern aviation infrastructure, parked commercial and military aircraft rely on an external power source to operate essential systems, avionics, air conditioning, and safety mechanisms without engaging the primary aircraft engines or auxiliary power units (APUs). While standard industrial and utility power networks operate globally at either 50Hz or 60Hz, airborne electrical architectures rely on 400Hz alternating current (AC). This specialized frequency is utilized because higher frequencies allow magnetic components—such as transformers, generators, and electric motors—to be built with significantly smaller cores and windings, dramatically reducing overall aircraft weight.
Our state-of-the-art solid-state (static) and battery-powered frequency converters efficiently transform standard municipal grid electricity (typically 3-phase 380V/400V/480V at 50/60Hz) into a stabilized, low-noise, and highly precise 115/200V AC 3-phase output at 400Hz. By reducing reliance on standard onboard APUs, airports and ground handling agencies can lower carbon emissions, eliminate fuel costs, and achieve noise-free maintenance bays.
From an engineering and regulatory perspective, modern digital cockpits and flight management systems are highly sensitive to power quality anomalies. Our manufacturing processes enforce a strict design standard: total harmonic distortion (THD) of our output voltage is limited to less than 2% under balanced linear load conditions, and less than 3% under non-linear conditions.
Furthermore, the dynamic transient response matches standard-defining protocols (such as MIL-STD-704F and ISO 6858). In the event of a sudden 100% load application or shedding, our solid-state converters recover the target output voltage within less than 15 milliseconds, protecting on-board radar, navigations systems, and flight instruments from harmful voltage spikes or drops.
Whether dealing with scheduled line maintenance or heavy base overhauls, hangar bays require flexible power delivery. Our static frequency converters can be installed as centralized ceiling-gantry systems, under-bridge apron units, or towable trailers, allowing mechanics to run tests without executing costly turbine burns.
Military aviation units demand strict adherence to rugged designs. Our military-grade 400Hz converters support aircraft like fighter jets, transport planes, and tactical UAV systems. They are designed to meet MIL-STD-810G requirements for vibration, shock, salt fog, and extreme operating temperatures (-40°C to +55°C).
During final assembly and integration testing, aerospace factories need reliable power. Our frequency changers feature precise adjustment of output voltages (up to 15%) and frequencies to simulate flight systems under varying conditions, ensuring complete validation before final delivery.
As the aviation industry works toward zero-emission taxiing and operations, the design of ground support equipment is changing. Here is how our engineering research is driving the next generation of ground power technology.
Traditional diesel-powered GPUs generate significant carbon emissions and noise on the tarmac. Our engineering roadmap prioritizes the deployment of hybrid and pure electric battery-powered GPUs. By combining high-capacity Lithium Iron Phosphate (LiFePO4) battery chemistry with solid-state 400Hz frequency converter technology, we deliver reliable power output without the fuel consumption or high maintenance costs of diesel engines.
Our latest 400Hz converters feature IoT-enabled telemetry systems. By continuously monitoring interior temperatures, load variations, semiconductor health, and insulation resistance, the system alerts airport operators of potential failures before they disrupt flight schedules. Integrated CAN bus architectures make it easy to monitor performance through central airport operations software.

Every component, including the heavy-duty structural steel plates in our dollies and the delicate power transistors in our static converters, is tracked using ERP systems to ensure complete traceability.
Furthermore, our factory features dedicated testing stations. Here, every 400Hz GPU is connected to an inductive load bank simulator to verify continuous power stability, harmonic levels, and heat dissipation under 100% capacity loads before shipment.
Every ground power unit undergoes testing on reactive and resistive load banks to confirm power factor capabilities and stable performance under surge currents.
Equipment built for coastal or marine environments is protected by hot-dip galvanizing and multi-layer polyurethane coatings to prevent rust and degradation.
Our manufacturing processes follow international quality guidelines to ensure the reliability of all civil and military ground support products.
