Abstract: A power module includes an input bus, a switching device, and an output bus. The input bus includes a first coating of a high permeability magnetic conductive material and is configured to receive input direct current (DC) electrical power from an electrical power source. The switching device is electrically coupled to the first input bus, and is configured to selectively connect and disconnect to facilitate converting the input DC electrical power into output alternating current (AC) electrical power. The output bus includes a second coating of the high permeability magnetic conductive material, and is electrically coupled to the first switching device. The output bus is configured to supply the output AC electrical power to an electrical load.

Abstract: A switch assembly includes one or more solid state semiconductor switches configured to be disposed within a downhole pipe assembly. The one or more switches are configured to operate in a closed state to conduct electric current supplied by a power source disposed above a surface to pumps disposed beneath the surface to cause the pumps to extract a resource from beneath the surface via the pipe assembly. The one or more switches also are configured to operate in an open state to stop conducting the electric current from the power source to the pumps.

Abstract: An electric machine with a low profile retention assembly for retention of a stator core is disclosed. A first housing houses the stator core. The first housing has an axial end face with a circumferentially extending, shaped profile having recessed portions that project axially inward alternating with non-recessed portions. A portion of the stator core extends axially out from the recessed portions. A core retention spring is disposed circumferentially at the axial end face of the first housing. The core retention spring has direct contact with the portion of the stator core that extends axially out from the recessed portions of the first housing and the shaped profile of the housing. The core retention spring pushes against the portion of the stator core that extends that extends axially out from the first housing, imparting one or more of an axial load and radial load into the stator core.
