DC-DC CONVERTERS FOR FUEL CELL APPLICATIONS

Importance of fuel cells

Fuel cells are crucial for achieving an efficient energy transition due to their clean and sustainable nature. Epic power designs and manufactures DC-DC converters for fuel cell applications.

However, their low-voltage DC output requires conversion to higher voltages for various applications. DC-DC converters play a vital role in adapting fuel cell outputs to match load requirements or interface with higher voltage DC buses, ensuring efficient and reliable power conversion.

Epic power fuel cell dc-dc converters

Epic power bi-directional DC-DC converters offer a comprehensive solution for all DC-DC conversions needed to design efficient fuel cell systems, including balance of plant components.

Both the isolated and non-isolated families of epic power converters provide users with complete access over all control modes, allowing for versatile customization.

These converters can be parallelized to scale up power as required, providing flexibility for various applications.

Collaborations with companies like Premel have resulted in highly adaptable solutions that meet the diverse needs of clients in the fuel cell industry.

Case study pilot plant

In Ghen Power´s plant, a 700V DC bus is created to design an off-grid fuel cell system.

This system is capable of starting from scratch using any battery and can also utilize the same battery for peak saving functions when the load requires rapid dynamics beyond what the fuel cell can provide.

The bidirectional functionality eliminates the need for external chargers, as batteries can be slowly charged through the same DC bus when excess energy is available from the fuel cell.

This integrated approach optimizes energy usage and storage, providing a flexible and efficient solution for off-grid applications.

Here is the schematic view of the installation.
