Infineon’s CoolSiC to supply components to Bloom Energy’s electrolyser

Bloom Energy to integrate CoolSiC MOSFETs and diodes for the power supply of their advanced, best-in-class fuel cell system.

Bloom Energy has chosen CoolSiC™ MOSFETs and CoolSiC diodes from Infineon Technologies AG to process electrical power in Bloom’s Energy Server, the company’s fuel cell offering, and the Bloom Electrolyzer.

The individual solid oxide fuel cells (SOFC) of the energy platform run on natural gas, biogas, or hydrogen. With high electrical efficiency, the system provides a continuous power supply that is robust to grid failures and weather conditions from -20°C to 45°C.

Compared to the previous silicon-based generation, this improved the system’s energy efficiency by 1% and power density by 30%. In addition, the system’s size and cost were reduced by 30%.

The CoolSiC MOSFET IMZ120R030M1H in a TO-247-4 package enables best-in-class switching and conduction losses. It offers a high threshold voltage of V th > 4 V. For simple and straightforward gate control, it features 0 V turn-off gate voltage. The device comes with a wide gate-source voltage range and a robust, low-loss body diode designed for hard commutation. It also offers temperature-independent turn-off switching losses.

The CoolSiC Schottky diode IDW30G120C5B comes in a TO-247-3 package and delivers an industry-leading forward voltage. In addition, the diode has no reverse recovery charge and delivers best-in-class surge current capability and excellent thermal performance.

Dr Peter Wawer, President of Infineon’s Industrial Power Control Division, said, “At Infineon, we are convinced that hydrogen is an excellent alternative to CO 2-emitting energy sources, making it an important tool in the decarbonisation of the energy industry and the automotive industry.”
