Abstract: A system and method for avoiding unintended acceleration is provided and includes a first integrated circuit-based electronic controller configured to receive acceleration and brake requests and provide a control output via a datalink dedicated to controlling a prime mover system of the vehicle, a three-axis accelerometer configured to provide acceleration outputs indicative of acceleration of the accelerometer relative to three dimensions, and a second integrated circuit-based electronic controller operative independently of the first integrated circuit-based controller configured to receive the acceleration and braking requests, receive the acceleration outputs of the three-axis accelerometer, and operatively coupled with the datalink. The second integrated circuit-based electronic controller is configured to determine an unintended acceleration event in response to the acceleration and braking requests, and the acceleration outputs of the three-axis accelerometer.

Abstract: A power converter apparatus includes a parent circuit board comprising a first surface, a second surface, and a thermal conductor core disposed intermediate the first surface and the second surface. A first child circuit is board mounted on the parent circuit board. A first plurality of power switches are mounted on the first child circuit board. A second child circuit is board mounted on the parent circuit board. A second plurality of power switches are mounted on the second child circuit board. A first heat transfer circuit includes a first set of conductors thermally conductively coupling the first plurality of power switches with the thermal conductor core. A second heat transfer circuit includes a second set of conductors thermally conductively coupling the second plurality of power switches with the thermal conductor core.
