摘要： Methods, system and apparatus are provided for reducing power loss in an electric motor drive system that includes an electric machine and an inverter module. A controller determines whether a torque command (Tcmd) is less than a minimum torque threshold (Tmin) that is required to disable the inverter module, and if so, increments a counter and determines whether the torque command (Tcmd) remains less than the minimum torque threshold (Tmin). When the torque command (Tcmd) remains less than the minimum torque threshold (Tmin), the controller checks to determine whether a current count value (n) maintained at the counter is greater than a count threshold (nth), and if so, the controller can generate a disable signal to disable switching within the inverter module.

摘要： In a motor controller, a modified interpolation technique uses an extrapolated torque command for the upper table to improve torque linearity under certain conditions. When the torque command input is greater than the max torque limit of a first look-up table, but less than the maximum torque limit of a second, adjacent look-up table, the desired current command is computed by interpolating between the maximum torque limit of the first table and a revised torque value for the second look-up table, wherein the revised torque value is determined by extrapolating from the maximum torque limit of the first look-up table through a torque value based on the torque command input.

摘要： Methods and apparatus are provided for determining whether one or more inverter sub-modules of an inverter module is operating properly. Amplitude of each stator current signal is regularly measured. For each current signal, a positive counter counts a number of consecutive times the amplitude of that current signal is less than a positive current threshold, while a negative counter counts a number of consecutive times the amplitude of that current signal is greater than a negative current threshold. If the positive counter or the negative counter exceeds a maximum count, it is determined that an inverter sub-module is operating abnormally.
