The inverter has been operating at 230kW from 800V of direct current (Vdc), with a power density of over 20kW/kg. This inverter performance is a large step change for the industry. The highly weight-efficient inverter technology is an integral part of the zero-emission, hydrogen-electric aviation engines that ZeroAvia is developing. Inverters take the DC-power supplied by the electric power source and convert it to Alternating Current (AC) while controlling the flow to electric motors. Such power sources can be hydrogen fuel cells (as in ZeroAvia engines), batteries, or even various hybrid systems. Hydrogen-electric systems are predicted to have the furthest reaching environmental benefits of all technologies considered practical for commercial aviation, with only low temperature water vapour exhaust.
