  • SYSTEMS AND METHODS FOR REDUCING ELECTRIC DRIVE NOISE, VIBRATION AND HARSHNESS
    Publication number: 20260200335
    Abstract: In an example embodiment, an electric drive system includes an inverter configured to convert a direct current (DC) voltage into an alternating current (AC) voltage for an electric machine; processing circuitry configured to cause the electric drive system to obtain parameters of the electric machine, obtain a mode of operation for the electric machine, the mode of operation related to at least one of noise, vibration and harshness, and control the electric machine based on the parameters of the electric machine and the obtained mode of operation.

  • Voltage sensor-less position detection in an active front end
    Patent number: 10295581
    Abstract: A controller including a memory having computer-readable instructions stored therein; and a processor configured to execute the computer-readable instructions to: estimate a synthesized grid voltage vector angle at a terminal of an alternating current (AC) grid based on at least an adjusted angle, to generate Pulse Width Modulation (PWM) signals to control power switches of the AFE inverter based on at least the synthesized grid voltage vector angle, and to control the AFE inverter to exchange power between the AC grid and a load based on the PWM signals.

  • Voltage sensor-less position detection in an active front end
    Patent number: 10270327
    Abstract: A controller may include a memory having computer-readable instructions stored therein; and a processor configured to execute the computer-readable instructions to generate Pulse Width Modulation (PWM) signals to control power switches of an Active Front End (AFE) inverter based on at least a synthesized grid voltage vector angle at a terminal of an alternating current (AC) grid without using physical voltage sensors at the terminal of the AC grid, and control the AFE inverter to supply power to a load based on the PWM signals.

  • Methods of generating output variable voltage for electric drive devices and systems thereof
    Patent number: 9553539
    Abstract: At least one example embodiment discloses a method of generating an output variable voltage. The method includes obtaining a selected mode of operation, the selected mode of operation being one of an voltage control mode and a frequency mode, determining an input voltage command based on the selected mode of operation, determining an input frequency command based on the selected mode of operation, adjusting at least one of the input frequency command and the input voltage command based on the selected mode of operation, generating a pulse width modulation reference based on the adjusted at least one of the input frequency command and the input voltage command and generating the output variable voltage based on the pulse width modulation reference.
