Abstract
SPWM techniques have been widely applied in the control of electrical machines. One of the problems of such inverter driven motors is the detrimental effect of a large amount of high-order harmonics. A precise estimation of the high-order harmonic field is of paramount importance for a thorough study of the performance of the motor when it is fed from SPWM. In this paper a 2-D multi-slice time stepping finite element method is proposed to model SPWM driven induction motors so that the high-order harmonic field can be directly included in the solution. To deal with the choice of the step size during the time stepping process when the motor is fed from a SPWM source, a method to adjust the step size according to the turn-on/turn-off time of the switches is presented. The method significantly reduces the integrating time as well as the error in the time stepping process.
