Patent ID: 11711003

Abstract:
An electric power supply is disclosed having high-voltage, direct-current (HVDC) circuitry comprising one or more DC pre-charge capacitors and one or more power transistor switches, the HVDC circuitry configured to receive high-voltage, direct-current (HVDC) input power of about 320 volts and/or greater and convert the HVDC input power to multi-phase, high-voltage, alternating-current (HVAC) output power of about 320 volts and/or greater; and low-voltage, direct current (LVDC) circuitry adapted and configured to operate on low-voltage, direct-current, wherein the LVDC circuitry is configured to control and monitor the multi-phase HVAC output power. The electric power supply is further configured to operate in reverse and convert received multiphase HVAC input power to HVDC output power.
