Abstract: Systems and methods to improve operation of a modular multilevel converter. Some embodiments include a first upper arm with a first active power link module, which facilitates producing a first portion of a first alternating current electrical power at a base frequency and injecting a first even-order current harmonic of the base frequency in the first upper arm, and a first lower arm with a second active power link module, which facilitates producing a second portion of the first alternating current, in which the first portion of the first alternating current and the second portion of the alternating current are combined to facilitate outputting the first alternating current electrical power at a first alternating current terminal, and injecting the first even-order current harmonic in the first lower arm, in which magnitude of the first even-order current harmonic is zero at the first alternating current terminal.

Abstract: A multilevel converter system is provided. The system includes a converter and a converter controller interfaced with the converter. The converter controller includes a voltage loop, a current loop, and a voltage compensation loop. The voltage loop is configured to receive first and second voltages from the first and second segments of the converter and a reference voltage. The current loop is configured to receive a current output of the converter, a reference current, and a balancing reference current. The voltage compensation loop is configured to receive the first and second voltages and a sign signal. The converter controller is configured to generate first and second pulse-width modulation (PWM) signals using output signals from the current loop and the output compensation signals from the voltage compensation loop. The PWM signals are configured to control the switches of the converter and to balance the first voltage with the second voltage.

Abstract: A method of controlling an electric motor assembly includes detecting a backspin event of an electric motor, and managing a response to the detected backspin event of the electric motor. The backspin event of the electric motor is detected based at least in part on feedback from a sensor configured to measure a current or a voltage on a cable coupled to the electric motor. The response includes communicating an alert to personnel, controlling the voltage on the cable to be less than a voltage threshold, or any combination thereof.

Abstract: A method includes controlling a first power output to an electric machine during a transient event. Controlling the first power output includes measuring values of the first power output provided to the electric machine during the transient event, receiving an estimated speed input of the electric machine, determining adjustment commands to compensate the first power output for the transient event of the electric machine, generating switch commands for gate drives of a variable frequency drive (VFD) based at least in part on the adjustment commands, and modifying the first power output during the transient event based on the switch commands.
