What's the real application here? It surely can't be automotive, the amount of time spent at full load is minuscule at least in cars. My old Model S has a full load output of 250 kW but the typical load is less than 30 kW. Lower power cars spend a bit more time at a higher fraction of full load but still typically far less than 50%.
Of course efficiency and cooling are important but EV drives are already quite efficient and rarely operate at full load so the improvement in practice will be small.
Or is the mention of automotive use relevant only because Porsche is involved in testing?
- lazide 3y ago100% duty cycle capable means more durable and capable of industrial use, racing, aerospace, military. Think mining haul trucks, industrial process control, towing, semi trucks, race cars, electric helicopters, water pumps, etc. also, likely capable of 150% for short bursts (military power)
- p1mrx 3y ago> also, likely capable of 150% for short bursts Existing inverters are already capable of 150% for short bursts, if you define 100% to be the constant full load capacity.
- lazide 3y agoAt 1MW?
- kwhitefoot 3y agoWhy not. 1.5 MW is only six times the maximum power of my ancient 2015 Model S 70D. The inverters are tiny.
- lazide 3y ago‘Only’ And not rated at 100% duty cycle probably?
- ju-st 3y agoThe 'full load' designation may be a distraction as the research appears to be focused on improving the cooling in general which obviously enables the use of less efficient and cheaper electronics.
