The first milestone on our journey to 35 kV has been achieved.
We are proud to announce the successful development of a high-isolation medium-frequency transformer for Solid-State Transformer (SST) applications, realized in close collaboration with Infineon.
This achievement marks an important step toward the next generation of medium-voltage power conversion systems up to the 35 kV isolation class.
Key Technical Specifications
● Rated Power: 100 kVA
● Resonant Frequency: 40 kHz
● Leakage Inductance: ≈ 150 μH
● Insulation Test Voltage: > 20 kV
● Partial Discharge Extinction Voltage (PDEV): > 14 kV
The development of high-isolation medium-frequency transformers is a key enabler for future SST architectures, supporting the electrification of energy infrastructure, renewable integration, and next-generation grid applications.
…the journey toward 35 kV continues.
