kW-Class Fuel Cell DC/DC Converter – SiC Technology
MW-Class Fuel Cell DC/DC Converter - IGBT Technology
Our fuel cell DC/DC converters are subjected to automotive-grade reliability trials: thermal cycling from -40°C to +85°C, vibration testing per ISO 16750, salt spray corrosion resistance, and comprehensive EMC pre-compliance — delivering field-proven durability for both stationary plants and on‑board vehicles.
The MW‑class IGBT series is designed for stationary fuel cell power generation (e.g., distributed power plants, backup systems). It uses IGBT technology with galvanic isolation, liquid cooling, and modular paralleling for capacities up to 10MW+. The kW‑class SiC series targets on‑board vehicle applications (buses, trucks, passenger cars). It uses silicon carbide (SiC) MOSFETs for higher switching frequency, higher power density, and peak efficiency up to 99%.
Yes. The MW‑class IGBT series is optimized for stationary power plants – it features rugged industrial design, forced air or liquid cooling, and can be paralleled for multi‑MW output. The kW‑class SiC series is designed for mobile applications – it is compact, lightweight, IP67 rated, and automotive‑grade with CAN2.0B communication.
MW‑class IGBT: ≥97.5% at rated load, with liquid cooling maintaining stable efficiency under continuous operation.
kW‑class SiC: Peak efficiency up to 99%, average efficiency >97% over typical drive cycles, significantly reducing thermal load and extending driving range.
MW‑class IGBT: 100% liquid cooling (water‑glycol) as standard; forced air cooling optional for lower power units.
kW‑class SiC: Liquid cooling is standard for high power density; optional integrated cold plate for vehicle thermal systems.
Both series operate reliably from -40℃ to +85℃ ambient.
