An electric motor assembly comprising a housing containing a secondary power source, a motor driver, an electric motor, power sensors to sense faults in a primary power supply and the secondary power source, primary and secondary winding sensors configured to sense faults in a primary winding and a secondary winding of the electric motor, the motor driver comprising a primary controller to control the primary winding in a normal operation mode and a secondary motor controller operatively configured to control at least one of the primary winding and/or the secondary winding in a secondary operation mode, the secondary motor controller configured to drive the motor to a safe position using the secondary winding in the event of a sensed fault in the primary winding and to drive the motor to the safe position using the secondary power source in the event of a sensed fault in the primary power source.

Fault tolerant actuator assembly

An improved apparatus for controlling and providing a pulse-width-modulated signal to a switch operatively arranged between two terminals of a power supply for controlling an output power. A controller provides a pulse-width-modulated gate signal at a frequency to the switch. The controller is arranged to adjust the frequency as a function of a sensed parameter such that the power dissipated in the switch during switch transitions may be adjusted.

Method and apparatae for controlling and providing a voltage converter with a pulse-modulated switch

The present invention provides an improved transformer (), which broadly includes: a substrate () having first and second surfaces (); a first board () mounted on the substrate first surface; a second board () mounted on the substrate second surface; the boards being identical to one another and being mounted on the respective proximate substrate surfaces as mirror images of one another; each of the boards having a plurality of dielectric layers with electrically-conductive sheet windings () embedded therein; and an assembled core () operatively arranged to provide a path for magnetic flux attributable to a current in some of the windings. Third and fourth boards () may be piggy-backed onto the first and second boards, respectively, to selectively vary the properties of the transformer.
