Does anybody else have this noise when they are in electric mode on their powerboost? is this the motor winding or the inverter?

Aux trans cooling pump most likely. There's at least 3 pumps and the AC motor that can run with the ICE engine off. The electric motor will run if in gear as well, but does time out if you're stopped for an extended period.
