Abstract: A power converter for a power system includes an input ceramic layer, an output ceramic layer, an input stage coupled to the input ceramic layer, an output stage coupled to the output ceramic layer, and a planar transformer coupled between said input stage and said output stage. The input receives a power input and the output stage generates a power output at least partially as a function of the power input. The planar transformer includes an input winding coupled to the input stage and an output winding coupled to the output stage. The input winding has a plurality of input turns and the output winding has a plurality of output turns. The input turns interleave the output turns.

Abstract: An approach for facilitating mechanical and electrical connection of electric machines and electrical components in an electrical system using connectors with quick connect/disconnect electrical connectors is disclosed. Each quick connect/disconnect electrical connector can be placed on the end of an electrical power distribution cable that connects with an electric machine or electrical component. The electric machines and electrical components and the electrical power distribution cables can have hollow coolant passages formed therein to receive cooling fluid from a cooling device for direct cooling of the electric machines, electrical components and the electrical power distribution cables.

Abstract: A method for shutting down a phase-leg of a three-level active neutral point clamped converter is provided. The method includes the following steps. A determining step determines if a switch fault has occurred, and if a switch fault has occurred then each switch of the plurality of switches are turned off. If a switch fault has not occurred and a shutdown is requested, then an operating step operates the plurality of switches to turn off a first switch and a fourth switch. A waiting step waits for a first predetermined time period. An operating step operates the plurality of switches to turn on a second switch and a third switch. A waiting step is repeated. An operating step operates the plurality of switches to turn off a fifth switch and a sixth switch. A waiting step is repeated. An operating step turns off the second switch and the third switch.
