Empa demonstrates hydrogen fuel cells for districts

Hydrogen fuel cells are fundamentally suitable for supporting power grids in district energy systems during peak load periods and for integrating hydrogen into building services systems. This is shown by a research project carried out by Empa, the Hälg Group, the Osterwalder Group, and H2 Energy AG. The project also focused on reducing CO2 emissions through the use of environmentally friendly hydrogen.

TDK enables 1250 V DC converters with high-voltage common-mode choke

TDK Corporation has presented the B82722V6*B040 series of new compact high-voltage, current-compensated ring-core double chokes. Designed primarily for rated DC voltages of up to 1250 V (630 V AC), these compact common-mode chokes (23 x 15.5 x 24 mm) effectively suppress EMI in next-generation applications. These include power converters, industrial motor drives, and switch-mode power supplies that often deploy SiC and GaN power semiconductors and feature elevated DC bus voltages, where insulation coordination and PCB space are critical.
