It's not that there is zero applicable knowledge transfer, but there are definitely some fundamental differences between digital components and analog power devices, in particular.
For digital, the transistor are CMOS, optimized to be as tiny as possible, running at < 1V, and with individual devices mostly driving microamps, going up to milliamps in some particular areas of the chip.
For power, we're talking about IGBTs, optimized to handle as much power as possible with maximum efficiency, at hundreds of volts.
They are both semiconductor devices, but they are about as similar as the engine for a sports car vs. for a panamax cargo ship.
