Abstract: A power conversion circuit having a solid-state circuit breaker integrated therein is disclosed. With a disconnect switch between a utility source and the power conversion apparatus described for meeting UL489, the power conversion circuit includes an input connectable to an AC source, a rectifier circuit connected to the input to convert an AC power input to a DC power, and a DC link coupled to the rectifier circuit to receive the DC power therefrom. The rectifier circuit comprises a plurality of phase legs each including thereon an upper switching unit and a lower switching unit, wherein at least one of the upper and lower switching units on each phase leg comprises a bi-directional switching unit that selectively controls current and withstands voltage in both directions, so as to provide a circuit breaking capability that selectively interrupts current flow through the rectifier circuit, while maintaining original power conversion functionalities.

Abstract: A motor driver control system is configured for connection to a plurality of motors, the motor control system includes a motor driver command module, and the motor driver command module is configured to: access information related to one or more operating metrics of the plurality of motors; analyze the information to determine whether a maintenance condition exists in any of the plurality of motors; and if a maintenance condition exists in any of the plurality of motors: prevent electrical power from reaching any of the plurality of motors, identify which one or more of the plurality of motors has the maintenance condition, disconnect the one or more identified motors from the motor driver control system, and restore electrical power to all of the plurality of motors other than the identified motors after disconnecting the one or more identified motors.
