Our second delivery includes:

• another high-voltage junction box with pyrofuses for electrical power distribution
• three additional high-power-density DC-DC converters, achieving a measured power density well beyond 20 kW/kg in the 450 kW class, targeting fuel cell and battery systems
• our first prototype of an HV/LV isolated DC-DC converter for aircraft applications, enabling triple-safe operation and delivering 11 kW peak power with 3×130 A capability 
• several partial-discharge-tested HV cables

In Nottingham (UK), Prof. Tao Yang and his team are currently setting up the propulsion sub-test with MW motor and inverter systems. This test campaign is an important step towards the 1 MW hydrogen-electric propulsion demonstrator, which will operate a propeller powered from a liquid hydrogen tank via a MW-class fuel cell system. That's how we are steadily approaching the completion of the full system demonstrator, scheduled for autumn at the Pipistrel Vertical Solutions acilities in Gorizia (IT).

From Germany to the UK and then Italy - We're amazed by this great European collaboration in NEWBORN, excellently coordinated by Honeywell Aerospace Technologies. Our power electronics team is happy to contribute!
