Solid-State Transformers (SST), there are those who talk and those who deliver!

Solid-State Transformers (SST) are widely discussed. But real achievements — like certified insulation performance and partial discharge below 10 pC — are what truly matter.

Traftor is proud to be among the first companies bringing mass-market-ready SST transformers that successfully pass all required validations in compliance with IEC 60076-3 and IEC 60270.

And most importantly:

All tests were performed and validated by an independent external certification center, as well as by two major global power-solution providers serving the data-center industry — ensuring full objectivity and industrial-grade validation.

60 kVA 30kHz SST Transformer – Validation Results

Insulation (Primary to Secondary)
– 42 kV AC / 1 minute / 15 mA — PASSED

Partial Discharge
– Pre-stress: 25 kV (~60 s)
– Measurement: 18 kV (~3 minutes)
– Result: < 3 pC — PASSED

Lightning Impulse
– 75 kV / 50 µs waveform, three consecutive shots — PASSED

These results confirm robust insulation design and reliability — key enablers for next-generation SST converters.
