Overview

As a leading manufacturer of power semiconductors for wind power and photovoltaic inverters, Infineon also drives renewable power generation. For the production of green hydrogen, very high direct currents (DC) are required in the electrolysis process. The alternating current (AC) supplied by the power grid must first be converted to DC, a process known as rectification or AC-DC conversion. Infineon offers ready-to-use rectifier semiconductor solutions for this purpose.

Infineon provides high-power semiconductors from Infineon for this conversion. Multiple synchronized high-power switches enable high combined system power (> 50 MW). If the electrolysis process is based on electricity from solar panels (which generate DC), only the DC voltage needs to be adjusted. The new thyristor stack design incorporates features necessary for water electrolysis and thus hydrogen production. The stacks are designed as half-bridges and can be used for complete B6C and B12C rectifier circuits. A system power of 10 MW rectifier power can be generated with three half-bridges. With this design, customers do not need to worry about semiconductor and fuse selection as they are already tested and certified.

This webinar will teach why the pre-defined thyristor stack solution is the optimal choice to enter the rectifier market and learn about optimized IGBT power modules for AC- and DC-coupled electrolyzer applications.
