    摘要： An adaptive gate drive for an inverter includes control circuitry having a Field Programmable Gate Array (FPGA) and includes power circuitry having a plurality of FETs for operating a switching device, such as a Trench Gate Insulated Gate Bipolar Transistor (IGBT device). The control circuitry provides switching signals for operating the switching device. In addition, the control circuitry receives signals of output current of the IGBT device, temperature of the IGBT device, and DC link voltage. The FPGA has a plurality of operating points stored therein. Each operating point has corresponding parameters for a control signal that is used to control the turn-on or turn-off behavior of the IGBT device. During operation, the control circuitry compares the measured current, voltage and temperature operating points stored in the FPGA and sends the corresponding parameters to the gate drive circuit. The gate drive modifies the signal on the gate of the IGBT accordingly and thereby optimizes the turn-on and/or turn-off behavior of the device based on actual operating conditions.

    摘要： A method of estimating rotor resistance by calibrated measurement of stator temperature is provided. The temperature of the stator winding may be monitored using a suitable device (thermistor, RTD etc). This temperature signal is used to “look up” the correct value of Rr for the current temperature. The “look up” characteristic is a calibrated table, whose values are learned during a prolonged test whereby actual (measured) motor torque is controlled to a correct demanded value by adaptation of the Rr parameter, as the motor temperature varies from cold to hot. The stator temperature feedback during the test provides the X-axis values of the look up table, and the correctly adapted Rr value provides the Y-axis values.
