Then it would be a range extender rather than an APU, but same idea.

Assuming the generator is 30% efficient (diesels generally do better) and the thermal recovery system can recover 80% of the...

Rather than run the APU at a fast idle just to get it making some heat, actually use it as a generator and make use of the power to run a heat pump, while still making use of the heat from the...

I just connected the resolver output signals (internally buffered) to the gates of the MOSFETs. The MOSFETs simply drive the two stator coils (2 phase unipolar motor) with two 1uF capacitors as...
