    摘要： Methods, apparatus and computer readable mediums are presented for controlling a multiphase inverter in which third harmonic injection pulse width modulation (THIPWM) is used for generating inverter switching control signals at or above a non-zero threshold inverter output frequency, and high frequency injection discontinuous pulse width modulation (HFIDPWM) is used for inverter output frequencies below the threshold, where the threshold frequency corresponds to a threshold period less than or equal to the thermal impedance time constant of the inverter switching devices, and the injected high frequency component for HFIDPWM corresponds to a common mode period less than the thermal impedance time constant to mitigate thermal stress on the inverter switches and low speed inverter output derating.

    摘要： A method for diagnosing the linkages of an inverter including a controller connected to switching devices that are between a DC input and a multi-phase output. The inverter can be diagnosed to determine whether the control signals provided to the switching devices are being properly provided to the inverter and whether the inverter is operating properly. Diagnosis of the inverter is advisable upon commissioning or after completion of a repair. The controller can provide at least one signal to the switching devices and the signal can be monitored adjacent to the switching devices to ensure that the switching devices are receiving the correct signals from the controller. The controller can provide at least one signal to the switching devices and the output of the inverter can be monitored to determine whether the inverter operates in accordance with the provided signal.
