Modern airport operations are undergoing a monumental paradigm shift. As environmental mandates intensify worldwide, aviation authorities are striving to achieve net-zero carbon operations at gate side terminals. The traditional approach of running an aircraft's onboard Auxiliary Power Unit (APU) while parked is increasingly being restricted due to high fuel consumption, excessive noise pollution, and heavy carbon emissions. This has led to the global standardization of Ground Power Units (GPUs) as the primary electrical interface for parked aircraft.
Aircraft Ground Power Supplies generally provide two critical electrical outputs: 400Hz AC power (typically 115V/200V) for larger commercial and military airplanes, and 28.5V DC power for turboprops, regional jets, and business aircraft. The global demand is shifting rapidly from legacy diesel-generator units toward highly efficient solid-state static frequency converters and innovative battery energy storage system (BESS) towable units. These technologies provide cleaner electricity, reduce total cost of ownership (TCO) for airlines, and support the integration of smart-grid topologies at modern airports.
The selection of an aircraft ground power system rests heavily on performance parameters, grid stability, and operational conditions. The table below outlines why solid-state frequency converters have become the industry standard compared to older diesel rotary systems.
| Technical Parameter | Solid-State (Static) GPU | Diesel Rotary GPU | Battery-Stored GPU (Next-Gen) |
|---|---|---|---|
| Efficiency | Up to 94% - 96% | 35% - 40% (Depends on load) | Up to 92% (Zero direct fuel burn) |
| Harmonic Distortion (THD) | < 2% (Strictly controlled) | 3% - 5% (Fluctuating) | < 1.5% (Extremely stable) |
| Noise Level | < 65 dB at 1 meter | > 85 dB (Requires acoustic housing) | Virtual silence (< 50 dB) |
| Maintenance Cost | Minimal (No moving parts) | High (Filters, oil changes, engine overhaul) | Low (BMS diagnostics, clean cell management) |
| Carbon Footprint | Indirect (Depending on grid supply) | High local diesel emissions | Zero localized emissions (Green airport fit) |
China is home to the world's most integrated electrical components, structural steel, and electronics supply chain, giving our factories unique industrial advantages.
Chinese Ground Support Equipment (GSE) and GPU factories utilize state-of-the-art automation, robotized welding, and digital testing laboratories to guarantee precision. By clustering supply networks for semiconductors, heavy structural fabrications, and magnetic components, our facilities dramatically decrease lead times while offering high-performance products at optimized price-to-quality ratios.
Additionally, our facilities strictly adhere to international quality and aviation protocols, including IATA AHM 910, AHM 913, and AHM 915. This compliance guarantees that our equipment seamlessly interfaces with global commercial airplanes (Boeing, Airbus, Embraer, COMAC) without risking safety or power surges.

Our lean manufacturing workflows allow us to fulfill bulk commercial orders within standard lead times, ensuring fast transit via ocean or rail.
We provide comprehensive OEM & ODM services globally. Our multilingual service network offers 24/7 technical assistance, spare parts, and remote diagnostic services.
Ground power installations must be optimized for localized climatic and operational environments. A GPU installed at a desert airport in the Middle East must withstand sandstorms and ambient temperatures exceeding 50°C, requiring IP65/IP66 rated enclosures, dual-fan thermal venting, and solar radiation shielding. Conversely, a unit operating at high latitudes (e.g., Northern Canada or Northern Europe) requires pre-installed sub-zero heating components to prevent electrolyte freeze-out in battery storage cells and mechanical stiffening in heavy power cables.
When procurement managers for global airlines (such as Lufthansa, Delta, or Singapore Airlines) choose ground equipment, they prioritize safety and versatility. Our units feature multi-voltage and dual-frequency flexibility (capable of running on 50Hz or 60Hz input grids while outputting steady 400Hz electricity). Furthermore, we feature high overload thresholds—capable of outputting up to 200% power for short intervals—to handle current spikes when starting onboard engines and cabin HVAC systems.
