I wanted to find out more about "silicon carbide inverters which biodirectionally convert high-voltage DC into three phase AC" (my underlining) but the site failed to produce when I tried to download further information...
IMV pretty much all the tech is mature enough and available for reliable electrically powered aircraft, the only real impediment being the energy source/density. Once that's resolved (and I'm not personally keen on 'fuel cells') things should move apace, but as I see it we're still some distance from that. Certainly don't see biology assisting much with things!
