Peak conversion efficiency
Per DC-DC module
Ultra-fast protection
Vehicle-to-grid ready
Built on power-electronics fundamentals
What we optimise for in every converter, charger and magnetics design — the engineering behind the numbers.
See it in the products →High-efficiency conversion
Up to 99% peak efficiency — less heat, smaller thermals, lower running cost.
Planar magnetics
Integrated planar transformers shrink the converter while raising power density.
Bidirectional · V2G-ready
Galvanic-isolated bidirectional DC-DC up to 25 kW for vehicle-to-grid and vehicle-to-load.
Ultra-fast protection
Over-current trip under 1.5 µs, plus over-voltage, over-temperature and short-circuit guards.
Wide power range
One engineering platform spanning 3 W gate supplies to 25 kW fast-charging modules.
Clean power / EMC
Current and voltage quality engineered to meet IEEE 519 and IEC 61000-3-2.
Engineered modules, ready to spec
From sample to production
KIMSEN is custom and quote-driven — no list prices. A clear path from first sample to volume.
Sample & Evaluation
Share your load profile and constraints; we match an existing module or sample to test against.
NRE / Custom Design
Where stock does not fit, we design to spec — power stage, planar magnetics, firmware and mechanicals.
Pilot & Validation
Pilot units undergo efficiency, thermal, EMC and protection validation before sign-off.
Volume Production
Validated designs move to repeatable volume manufacturing with consistent quality.
