Time-Domain, Steady-State Torque Calculation of Voltage-Source Pulse-Width-Modulated Inverter Fed Induction Motors
Evaluation of torque pulsation associated with the harmonics of pulse width modulated (PWM) inverter-fed drives is important, particularly at low speed. This paper discusses an analytical method for the steady-state torque calculation of the voltage-source PWM inverter fed induction motors. Equations derived from the 1-2-0 coordinate system are used. A sample calculation is included for the illustration of practical application.
