1. An electric power supply, the electric power supply comprising:
direct-current (DC) to alternating-current (AC) circuitry adapted and configured to receive DC power input having a DC input voltage of about 320 DC volts to about 820 DC volts and convert the DC power input to multi-phase, alternating-current (AC) power output that ranges from ten (10) Hertz to as high as a thousand (1000) Hertz,
wherein the DC to AC circuitry further comprises:
at least two DC capacitors; and
an electromagnetic interference (EMI) noise filter to suppress EMI noise, wherein the EMI noise filter comprises two, electrically insulated, conductive rails configured side by side as a linearly extending shaft having a length and a cross-section and adapted to receive the DC power input, ferrite material formed as one or more elements substantially circumscribing the two conductive rails and extending a majority of the length of the two conductive rails, and a current sensing element positioned in a gap in the one or more elements formed of ferrite material and configured to measure leakage current escaping to ground,
wherein the two electrically insulated, conductive rails of the EMI noise filter are physically located and extend lengthwise at least partially between the at least two DC capacitors and delivers the DC power input to the at least two DC capacitors.
