  • Patent number: 12057798
    Abstract: According to some embodiments, method for controlling a motor comprises generating a drive signal for the motor, the drive signal comprising a demand flux generating voltage parameter. A feedback torque generating current parameter and a feedback flux generating current parameter are determined based on a three-phase motor current measurement. A feedback flux generating voltage parameter is determined based on the feedback torque generating current parameter and the feedback flux generating current parameter. An estimated motor position and an estimated motor speed are determined based on the feedback flux generating voltage parameter and the demand flux generating voltage parameter. The drive signal is generated based on the estimated motor position and the estimated motor speed.

  • Patent number: 11901888
    Abstract: A gate charge profiler for a power transistor may include a voltage comparator unit and a timer unit. An input signal may control a gate drive current input to a gate of the power transistor to control conduction between a drain and a source of the power transistor. The voltage comparator unit may be configured to compare an input voltage and a threshold voltage, and to output a comparison signal. The input voltage may be a drain-source voltage across the drain and the source of the power transistor or a gate-source voltage across the gate and the source of the power transistor. The timer unit may be configured to output a time value based on input of a transition of the input signal and input of the comparison signal.

  • Patent number: 11728753
    Abstract: According to some embodiments, a method for controlling a motor comprises generating a stall threshold based on a torque generating current parameter associated with the motor. A motor stall condition is identified based on a torque generating voltage parameter associated with the motor violating the stall threshold. Operation of the motor is adjusted responsive to identifying the motor stall condition.

  • Patent number: 11728752
    Abstract: A method of driving a permanent magnet synchronous motor (PMSM) with Field Oriented Control (FOC) includes: generating, by a current controller, control signals for driving motor currents of the PMSM; measuring, by the current controller, current information of the PMSM, including a direct-axis motor current and a quadrature-axis motor current; generating, by a direct-axis current controller, a direct-axis error value based on a difference between a flux weakening reference current and the direct-axis motor current; regulating, by the direct-axis current controller, a direct-axis motor voltage, including generating the direct-axis motor voltage based on the direct-axis error value; and generating and dynamically adapting, by a flux weakening controller, the flux weakening reference current based on changes to the motor load.
