There is not much they can show to really lead besides switching to superior switches.
I admit Tesla's inverter design is very conservative, but it's very thorough engineering.
- londons_explore 5y agoI'm really surprised you don't see the inverter and the motors closer coupled in Tesla's designs. For example, by having MOSFETs spliced into the wire wound onto the stator. That minimises wire length (and therefore resistance). The heavy motor windings are a great heatsink for brief acceleration, and both will need liquid cooling for prolonged 100 mph driving up a hill.
- baybal2 5y agoAlmost all high power switches are made to be soldered directly to cables.
- madengr 5y agoThe article mentions GaN not widely used because it is integrated with Si. Cree’s process is GaN on SiC, so you’d get better heat dissipation than in Si, but it costs more. There are also done processes integrating a diamond heat spreader under the GaN channel.
