First Schottky diode for high-voltage DC links

Infineon has created the first 2000 V Schottky diode for high-voltage (HV) DC link designs, writes Nick Flaherty.

The CoolSiC 2000 V G5 is the first discrete silicon-carbide diode with this breakdown voltage, making it suitable for DC links up to 1500 V with current ratings from 10-80 A. This makes it ideal for higher DC-link voltage applications.

ICEBreaker hydrogen HGV

Two companies have teamed up to build a hydrogen-powered HGV using a fuel-cell powerplant, as Peter Donaldson reports.

Spearheaded by powertrain energy-management specialist Viritech, Project ICEBreaker has built a hydrogen-powered heavy goods vehicle (HGV) using a fuel-cell power plant, focusing on minimising the weight penalty compared with internal combustion engine (ICE) vehicles.

Halevai electric boat

Halevai is on a mission to redefine the recreational marine market, combining an electric powertrain with a trimaran hull, reports Will Gray.

It might look like a relatively ordinary recreational day cruiser, but in an industry that is traditionally as slow moving as a heavily loaded tanker, the design of Halevai’s model2050 – which pairs an innovative but highly standard electric powertrain with an ultra-efficient trimaran hull – places it firmly in the ‘ground breaker’ category.

Battery dielectric protection

Peter Donaldson examines multi-function dielectric materials for battery systems.

Dielectric protection materials are critical in EV battery systems, where they serve to insulate components from one another, reduce the risks to technicians working on them, and often also contribute to structural strength and thermal management.
