Fuel-Cell DC/DC Boost Converter
Next generation efficiency and reliability with Infineon products for fuel-cell DC/DC converter applications
The fuel-cell DC/DC boost converter plays a crucial role in the operation of fuel-cell electric vehicle drivetrain systems. A FC electric drivetrain system comprises of at least one DC/DC boost converter, which interlinks the fuel-cell stack with the DC link voltage of the traction inverter and the high-voltage traction battery. The fuel-cell DC/DC converter enables the energy flow between these two electrical subnets over a wide voltage range.
At Infineon, we understand that all sub-systems of fuel-cell electric vehicles need to maintain the highest possible levels of efficiency and reliability while staying cost-effective. This, in combination with the need to keep DC/DC converter dimensions to an absolute minimum, are just some of the challenges facing system designers today. That is why Infineon offers a broad range of chip-set solutions intended to optimize and support the design of DC/DC converters in fuel-cell technology.
