Inverter supply is known to create additional power losses in an induction machine over those occurring with grid supply. The extent and nature of that increase are examined here for a switching frequency representative of current practice. Data are obtained from a time-stepped finite element analysis (FEA) model of the machine, coupled to circuit equations that include a model of the switching action of the inverter. A variable time-step algorithm is used to ensure accurate representation of… CONTINUE READING
