Thyristors save space in charger

Littelfuse has developed a reference design for a 2 MW bidirectional fast charger for commercial vehicles (writes Nick Flaherty). Rather than using MOSFETs, the 12-pulse thyristor stack can support a 2 MW output in a smaller volume with just forced-air cooling. Five 70 kW modules using thyristors that are stacked to provide 350 kW occupy 0.175m³, excluding any pumps and radiators needed for cooling the circuit. For a dual 350 kW charger, the minimum space consumed is a cube with 1.5 m sides and a volume of 3.4m³.
