The Problem We Solve

Conventional Power Conversion Is Reaching Its Limits

Grids and energy systems were designed for one-way, passive power flow. Today's loads — AI data centers, EV fleets, renewables, storage — need something different: efficiency, controllability and bidirectional power.

Cut System Losses

Conventional transformer + converter stages lose 3–8% of energy. SiC-based SST conversion reaches >99% efficiency at full load — less heat, less cost per megawatt.

Shrink Footprint & Weight

Line-frequency transformers are heavy and slow. High-frequency conversion with SiC delivers the same power at a fraction of the volume — critical for data centers and urban sites.

Add Grid Services

Voltage regulation, harmonic filtering, power-quality control and reactive support become native functions — not add-on equipment — in a solid-state transformer.

Enable DC & New Loads

Direct DC output feeds AI data centers, EV chargers and storage without extra conversion. Bidirectional flow turns a transformer into an active grid asset.

Applications

Built Around Your Application, Not the Other Way Around
