Abstract
The paper presents a technique for the offline optimization of pulse patterns applicated in controlling high performance drive systems with an induction motor fed by low switching voltage source inverters. The amplitudes of torque harmonics are used as criteria for optimizing pulse patterns besides the value of stator winding losses and the amplitudes of current harmonics. Furthermore synchronous pulse patterns without 90°-symmetry in their courses are offered allowing the variation of amplitudes and phase angles of current harmonics. This is advantageous for eliminating several torque harmonics
