SST
Next-generation power conversion — replacing bulky iron-core transformers with intelligent, bi-directional, high-frequency solid-state devices.
Next-generation power conversion — replacing bulky iron-core transformers with intelligent, bi-directional, high-frequency solid-state devices.
A Solid-State Transformer (SST) uses high-frequency power electronics (SiC MOSFETs, IGBTs) to perform voltage conversion — replacing the traditional copper coils and iron core.
The result: 50-70% smaller footprint, bi-directional energy flow, and full digital control of voltage, current and power quality.
HVDC supply — compact, high-efficiency power delivery for hyperscale computing loads with fewer conversion stages.
480 kW – 1 MW ultra-fast charging stations; direct MV connection removes the line-frequency transformer and substation room.
Multi-port interconnection of PV, storage and loads with real-time power quality control and bi-directional dispatch.
Epoxy-potted body with direct copper-bar terminals and class-H insulation. Available as fully potted or coil-potted builds, with natural or forced-air cooling.
