Abstract

In this paper, a harmonic elimination and suppression scheme for a dual-inverter-fed open-end winding induction motor drive is presented. Two isolated dc-link sources with voltage ratio of approximately 1: 0.366 are required for the present drive. These two isolated dc links feeding two inverters to drive the open-end winding induction motor eliminate the triplen harmonic currents from the motor phase. The pulsewidth-modulation scheme proposed enables the cancellation of all the 5th- and 7th-order ($6_n$ \pm 1, where n = 1, 3, 5, 7 etc.) harmonic voltages and suppresses the 11th- and 13th-order harmonic voltage amplitudes in the motor phase voltage, in all modulation ranges. The next higher order harmonics present in the motor phase voltages are 23rd, 25th, 35th, 37th etc. ($6_n$ \pm 1, n = 4, 6, etc.). By using triangular carrier wave and proper modulating waves for each inverter, the open–end winding induction motor can be operated in the entire modulation range, eliminating all the $6_n$ \pm 1 harmonics (n = 1, 3, 5, 7 etc.) coupled with 11th and 13th harmonic suppression. The proposed scheme also gives a smooth transition to the overmodulation region.
