    摘要: Current source converters and control methods are presented for high dynamic performance by implementing a DC link current control loop parallel to one or more motor control loops, with a DC link current control command value for operating the current source rectifier being derived at least partially independent of the motor control command values, wherein certain implementations drive the current source rectifier to its maximum rated value, or the DC current command value can be set above an amount required by the current source inverter using a gain factor which can be fixed or can itself be adjusted based on one or more motor control error values for balancing as-needed dynamic performance and efficiency.

    摘要: Apparatus and methods are provided for detecting degradation of delta-connected filter capacitors in an active front end (AFE) power converter, in which delta circuit capacitor leg currents are calculated based on measured branch circuit currents, and filter capacitor impedance values are computed based on the calculated leg currents as well as measured line-to-line voltages and corresponding phase angles for comparison with one or more thresholds to selectively detect degradation of the filter capacitors. Further apparatus and methods are provided for detecting degradation of Y-connected filter capacitors by computation of fundamental frequency RMS impedance values as ratios of RMS capacitor voltages and RMS circuit branch currents, and comparison of the calculated RMS impedance values with one or more thresholds.

    摘要: Motor drives and control methods are presented for sensorless motor speed control in which inverter output currents are sampled from the inverter output and a frequency modulation value is determined based on the current feedback. A speed or frequency setpoint is adjusted at least partially according to the frequency modulation value to provide an adjusted frequency or speed setpoint value that is then used in controlling the inverter to provide stability control to mitigate hunting or motor stoppage.
