Abstract: The subject matter described herein includes a multiphase fractional slot concentrated winding machine. One such machine includes a machine module including a rotor and a stator. The stator includes a plurality of radially extending teeth. Each tooth is individually wound with a coil. The machine further includes a multiphase series converter circuit physically connected to an end of the machine module to energize the coils for multiphase operation.

Abstract: In one aspect, a modular static transfer switch is provided. The module static transfer switch includes an output configured to couple to a load, a first input configured to couple to a first power source, and a second input configured to couple to a second power source. The modular static transfer switch further includes a plurality of sold-state switch modules each comprising at least one solid-state switch. A first plurality of the solid-state switch modules are coupled in parallel between the first input and the output, each configured to selectively couple the first power source to the output using the at least one solid-state switch. A second plurality of the solid-state switch modules are coupled in parallel between the second input and the output, each configured to selectively couple the second power source to the output using the at least one solid-state switch.
