OSKAR® is a highly dynamic, active three-phase voltage restoration system designed to stabilize industrial power networks and protect all applications that rely on absolutely disturbance-free supply conditions. The system continuously monitors the grid voltage and compensates deviations such as dips, swells, unbalance, or phase shifts in real time.

With its advanced power electronics, OSKAR® corrects the output voltage within milliseconds, ensuring that sensitive loads continue to operate without interruption even under severe voltage disturbances.

Key features:

• High-dynamic voltage regulation: Fast and precise compensation of voltage dips and transient disturbances.

• Stabilized magnitude and phase: Full control of the three-phase voltage waveform, even under heavy unbalance.

• Modular and scalable: Power range can be expanded up to very high MVA ratings through simple module addition.

• High efficiency: No large energy storage required, resulting in low losses and low maintenance costs.

• Robust and fail-safe: Maintains nearly full short-circuit current capability and provides automatic bypass in case of faults.

Typical applications include semiconductor and pharmaceutical production, high-precision measurement and testing environments, hospitals, data centers, and all mission-critical industrial processes where stable voltage is absolutely essential.

OSKARlinchen brings the proven functionality of the OSKAR® system into a compact device designed for lower power ranges and decentralized applications. As a prototype, it follows the same objective as the full-scale system: providing effective protection of sensitive equipment against voltage disturbances and instability.

Key characteristics:

• Compact design: Ideal for installations with limited space or where a full-sized DVR would be excessive.

• DVR functionality for low-power loads: Active stabilization of voltage magnitude and phase for individual machines or small-scale sensitive equipment.

• High dynamic response: Built on the same fast-acting control principles as the OSKAR® platform.

• Wide application potential: Suitable for OEM integration, laboratories, test benches, or as a local protection solution for highly sensitive loads.

Final power ratings and configuration details will be provided as the prototype progresses toward commercialization.

GridClass®-Mod is a flexible, standardized modular system concept that combines various filtering, damping, and compensation technologies to achieve comprehensive improvement of grid power quality – from base-load operation to the suppression of high-frequency disturbances.

The modules can be used individually or in combination and cover a wide range of functions, from classic reactive-power compensation to the elimination of complex resonance conditions.

Functional highlights:

• Broadband filtering: Effective against harmonics, supraharmonics, and grid resonances.

• Modular architecture: Each module can be easily integrated, expanded, or replaced – ideal for switchgear builders and system integrators.

• Innovative technology mix: Includes

  • SOFIA®-mod – intelligent filter modules,

  • RESI-mod – resonance elimination systems,

  • SIMΩN® – active damping and dynamic reactive current compensation,

  • CLASSIC-mod – proven classical compensation technology.

• Plug-and-play integration: Standardized modules enable fast project planning, installation, and commissioning.

GridClass®-Mod is a future-proof solution for modern networks increasingly affected by non-linear loads, converter-based equipment, and decentralized energy production.

SIMΩN® is a next-generation active power-quality system. Using advanced silicon-carbide power semiconductors, it combines grid-filtering, resonance damping, and dynamic reactive-current control in a single modular device.

Core functions:

• Broadband resonance damping: Suppresses oscillations and resonance effects across a wide frequency range.

• Active harmonic filtering: Injects compensating currents to significantly reduce harmonic distortions.

• Highly dynamic reactive-current compensation: Ensures fast stabilization of power-factor and voltage behavior.

• Modular and scalable: Can be adapted to specific power ranges, frequency bands, and industrial requirements.

SIMΩN® is particularly suitable for high-tech manufacturing, data centers, energy-storage and PV systems, test fields, and any application requiring the highest standards of power quality.
