Infinity Flow – has successfully completed validation testing of its Generation 4 Solid-State Transformer (SST) module, achieving 98.3% efficiency at full power and demonstrating ultra-fast bidirectional transient performance.

The test campaign validated the company’s core tri-port CLLC / Dual Active Bridge isolation architecture, confirming stable operation under both steady-state and dynamic conditions.

Key Results

• 98.3% measured efficiency at full power

• Stable bidirectional energy transfer (HV ⇄ LV)

• Clean semi-resonant operation with optimized circulating current

• Transient performance significantly exceeding the original design target

The sub-millisecond bidirectional response demonstrates strong control bandwidth and robust resonant tank behavior, critical for modern grid-interactive applications.

Enabling Next-Generation MV Infrastructure

High efficiency combined with fast dynamic response is essential for:

• AI data centers

• Utility-scale renewable integration

• Battery energy storage systems

• EV fast charging and V2G

• Grid modernization platforms

These results further validate Infinity Flow’s modular MV-SST architecture as it advances toward full-system, multi-megawatt deployment.
