Localized High-Voltage Application Scenarios in Graz & Styria
As Austria’s automotive heartland, green-technology innovation basin, and microelectronics nexus, Graz requires power conversion architectures that perform beyond catalog limitations.
Automotive E-Mobility & Dyno Bench Testing
Within the automotive clusters spanning Graz, Raaba, and Sankt Valentin, powertrain engineers require 800V to 1200V bidirectional and high-voltage programmable DC power supplies to simulate dynamic lithium-ion battery packs, wide bandgap SiC inverter stresses, and e-axle endurance under regenerative braking cycles.
Semiconductor Bias & Thin-Film PVD
Aligning with Styria's Silicon Alps semiconductor corridor, our high-voltage low-ripple DC units provide crucial bias voltages for magnetron sputtering, plasma-enhanced chemical vapor deposition (PECVD), and ion implantation chambers, operating with arc-suppression response times under 10 microseconds.
Green Tech & Hydrogen Water Electrolysis
Graz's Green Tech Valley pioneers megawatt-scale PEM and alkaline water electrolyzers for green hydrogen. Our heavy-duty continuous DC rectifiers deliver stable, ultra-high currents (up to 15,000A) with water-cooled thyristor or IGBT topologies designed to withstand 24/7 electrochemical continuous duty cycles.
Cataphoretic Dip Painting (KTL) & Anodizing
Contract automotive manufacturers and surface finishers in Styria demand zero-defect cathodic electrodeposition (KTL) and titanium hard anodizing. Our adjustable voltage systems provide precise soft-start voltage ramps up to 400V DC to prevent paint ruptures, pinholes, and uneven oxide coating layer thickness.
Aviation Hangar GSE & Radar Testing
Supporting MRO operations at Graz Airport (Thalerhof) and regional aerospace defense suppliers, our 400Hz static frequency converters and 28.5V DC Ground Power Units (GPUs) provide clean, low-distortion, stable auxiliary power for avionics verification, flight navigation maintenance, and turbine cranking.
Electrospinning & Academic Laboratory R&D
Research hubs like Graz University of Technology (TU Graz) and JOANNEUM RESEARCH utilize our modular 30kV to 100kV capacitor chargers and low-current supplies for electrospinning functional polymer membranes, developing ceramic solid-state battery separators, and high-voltage dielectric breakdown assays.
Key Technical Insight for Styrian Facilities
Unlike standard off-grid or unregulated AC grids, Graz industrial zones require power sources with low total harmonic distortion (THD < 5%) to comply with Austrian grid utility codes (ÖVE/ÖNORM EN 50160). Our active power factor correction (PFC > 0.98) eliminates reactive power surcharges on high-capacity industrial power contracts.
Market Trends Shaping Power Supply Procurement in Graz
Technological transformation across Southern Austria creates specific hardware specifications that high-voltage converters must meet over the next decade.
Migration to 800V SiC Architectures
Styrian automotive development leads the European transition from 400V to 800V/1000V silicon-carbide architectures. Test benches now mandate power supplies capable of rapid voltage ramping and wide continuous operating envelopes without transformer reconfiguration.
Closed-Loop DI Water Cooling
In cleanroom surface finishing and clean tech plants, fan-forced cooling brings particulate contamination and high noise levels. Water-cooled rectifiers integrated into central chiller networks are rapidly becoming standard across modern Graz production facilities.
Unified Fieldbus Protocol Stacks
Austrian plants heavily favor Siemens and Beckhoff automation ecosystems. Power systems must provide real-time fieldbus interfaces such as Profinet, EtherCAT, and Modbus-TCP alongside traditional analog 0-10V/4-20mA lines to enable lights-out operations.
Stringent Carbon & Energy Audits
Under Austrian energy efficiency statutes (EEffG), low-efficiency SCR rectifiers (75-80%) are being decommissioned. Switched-mode IGBT rectifiers operating consistently above 90% system efficiency provide measurable return on investment through reduced factory cooling loads.
