Solid State Transformer
A project-configured power electronic transformer for MV to DC conversion, MVDC systems, data centers, EV charging infrastructure and microgrids.
What is a Solid State Transformer?
A Solid State Transformer, or SST, combines controlled power electronic conversion with high-frequency isolation. It changes voltage and can convert between AC and DC while providing controllable interfaces for the wider electrical system.
| Conventional transformer | Solid State Transformer |
|---|---|
| Line-frequency magnetic voltage transformation | Actively controlled conversion stages with high-frequency isolation |
| Primarily AC input and AC output | Project-specific AC and DC interfaces |
| External equipment provides most power control functions | Power conversion and control functions are integrated into the architecture |
Final configuration depends on project voltage level, power rating, DC bus requirement, topology and application.
Why use SST for medium-voltage power conversion?
SST can create a controlled conversion path between a medium-voltage source and the required AC or DC distribution bus. This can reduce the number of separate conversion interfaces in some architectures and enable bidirectional or multi-port operation where the project requires it.
Where can SST be used?
DC distribution
Conversion between MVAC, MVDC and lower-voltage DC buses within a coordinated system design.
EV charging infrastructure
Medium-voltage connection and DC distribution for high-power charging hubs.
Renewable energy & microgrids
Controlled AC/DC interfaces for generation, storage and local DC loads.
Industrial DC systems
Project-specific DC supply architectures for industrial processes and power electronic loads.
Multi-port energy systems
Coordinated power flow across required AC and DC interfaces.
Engineering FAQ
SST and power architecture
What is a Solid State Transformer?
An SST is a power electronic conversion system that combines controlled conversion stages with high-frequency isolation to change voltage and, where required, convert between AC and DC.
How is an SST different from a conventional transformer?
A conventional transformer changes AC voltage through line-frequency magnetic coupling. An SST adds actively controlled conversion, allowing project-specific AC or DC interfaces and system control functions.
What is MV to DC power conversion?
MV to DC conversion connects a medium-voltage AC source to a defined DC bus through controlled and isolated power conversion stages. Voltage level, grounding, protection and redundancy must be designed as one system.
Why use SST in data center power architecture?
An SST can provide a direct medium-voltage conversion path to a required DC bus and support an integrated DC distribution architecture. Suitability depends on the complete electrical design.
