Perhaps you would like to know more?

What is an MW-Class Fuel Cell DC/DC Converter used for?

This converter steps up the low-voltage, variable DC output from fuel cell stacks to a stable, higher-voltage DC bus (e.g., 800V), which then feeds a grid-tied inverter or directly powers loads. It is designed for MW‑scale stationary fuel cell power generation, such as distributed power plants, data center backup, or industrial cogeneration.

How many fuel cell inputs does this DC/DC converter support?

The unit supports up to four independent inputs, each rated at 500kW and 1000A maximum. This allows connecting multiple fuel cell stacks or modules to a common DC bus, improving system redundancy, scalability, and fault tolerance.

What is the typical efficiency of this converter?

The converter achieves ≥97.5% efficiency at half load and above. By using IGBT technology with optimized switching and soft‑commutation techniques, it minimizes power losses even at high output levels, reducing operating costs and cooling requirements.

Can multiple DC/DC converters be paralleled for larger power output?

Yes. The modular design supports easy parallel expansion via digital current‑sharing control. Multiple units can be connected to increase total power from 1MW to tens of MW, making it suitable for large‑scale fuel cell power plants.

What output voltage levels are available?

The converter provides a regulated 800V DC output bus. This is a standard voltage level for modern grid‑tied inverters and industrial drives. For other voltage requirements, customization is available (contact our engineering team).
