Localized Applications Across the San Jose & Bay Area Aviation Belt
From San José Mineta International (SJC) apron operations to advanced eVTOL test benches in Silicon Valley research parks, Fenvix GPUs solve critical power quality challenges.
San José Mineta (SJC) FBOs
Fixed Base Operators catering to private jet corridors (Gulfstream G650, Bombardier Global, Citation Latitude) utilize our ultra-silent 28.5V DC cart units to conduct pre-flight checks, avionics diagnostics, and cabin cooling without running Auxiliary Power Units (APUs).
Silicon Valley eVTOL Labs
Pioneering Advanced Air Mobility (AAM) innovators in Santa Clara and Sunnyvale rely on our programmable DC systems and 400Hz frequency converters to simulate airborne bus power, high-voltage battery charging circuits, and rotor flight controls under controlled electrical parameters.
Moffett Field & Defense MRO
Flightline MRO centers adjacent to Moffett Federal Airfield demand robust, MIL-STD compliant 400Hz 115V power conversion capable of delivering 300% overload capacity to support specialized defense electronics, transport utility systems, and heavy turboprop starting.
Reid-Hillview Aviation Hubs
Flight academies and airframe repair shops operating out of San Jose's Reid-Hillview Airport (RHV) implement our compact 220V single-phase 28.5V rectifiers for general aviation battery conditioning, glass-cockpit avionics calibration, and continuous ramp maintenance.
Decarbonization, Zero-Emission Ramps & Solid-State Power Conversion
Technical analysis on why Northern California airport operators and municipal leaders are retiring diesel generators in favor of stationary and mobile solid-state IGBT ground power infrastructure.
1. The Electrification Mandate at San José Mineta International Airport (SJC)
The Bay Area Air Quality Management District (BAAQMD) along with California's stringent Title 24 energy mandates have placed unprecedented regulatory pressure on airport ground handlers and FBO operators. San Jose's corporate climate targets dictate an aggressive reduction in diesel emissions within ramp operations. Historically, diesel-driven ground power units emitted significant levels of particulate matter and NOx during standard 45-minute aircraft turnarounds. Modernizing to solid-state static frequency converters and point-of-use AC/DC rectifiers eliminates direct emissions at the gate while cutting operating energy overhead by up to 42%.
2. Solving Harmonic Injection into Sensitive Silicon Valley Microgrids
Corporate hangars and aeronautical testing centers surrounding San Jose frequently share distribution feeders with microelectronics fabrication plants and massive hyperscale data centers. Standard non-linear power supplies often reflect high Total Harmonic Distortion (THD) back into the 480V 60Hz utility feeder, triggering localized voltage sags and tripping sensitive semiconductor manufacturing equipment.
Fenvix Ground Power Units are engineered with active power factor correction (PFC > 0.99) and 12-pulse or multi-stage active harmonic filtering topologies. This guarantees that current harmonic feedback (THDi) remains strictly below 3%, adhering completely to IEEE 519 standards required by Silicon Valley municipal utilities such as San José Clean Energy (SJCE) and PG&E.
3. Engineering for Next-Gen Urban Air Mobility (UAM) and Hybrid Architecture
The concentration of Advanced Air Mobility (AAM) pioneers along Highway 101 and the San Jose tech corridor has transformed ground equipment criteria. Unlike legacy airliners that merely require auxiliary power for avionics, emerging eVTOL airframes demand dual-purpose GPU systems capable of delivering precision 28.5V DC for avionics checkout alongside programmable high-voltage DC (up to 800V DC) for fast-charging high-density airborne battery packs. Fenvix bridges this exact engineering divide with custom multi-bus architecture.
| System Specification | Legacy Diesel-Driven Cart | Motor-Generator (Rotary) Set | Fenvix Solid-State GPU (IGBT) |
|---|---|---|---|
| Operating Efficiency | 68% – 74% (Fuel to Electric) | 78% – 82% | 93% – 95.5% (High Frequency) |
| Direct Ramp Emissions | High (CO2, NOx, Soot) | Zero (Requires Grid Feed) | Zero Emissions (CARB Compliant) |
| Acoustic Footprint | 84 – 92 dBA at 7 meters | 76 – 82 dBA at 1 meter | ≤ 65 dBA (Hangar Friendly) |
| Transient Voltage Recovery | > 50ms (Slow Governor) | 30 – 40ms | ≤ 2ms (Microsecond Loop) |
| California Title 24 Compliance | Non-Compliant / Phased Out | Marginal Grid Efficiency | Exceeds Energy Mandates |
