Authors has proposed a multiple 5-level type inverter as a power converter for driving LSM. The output voltage of the inverter for driving LSM contains a large quantity of harmonics inherent to its control. Harmonics contained in the output voltage cause a harmonic resonance in the feeding circuit which is composed of feeding cable and armature coils. Moreover, the harmonics may induce communication interference. Therefor, the quantity of harmonics generated from the inverter has to be reduce. This paper presents a control method of multiple 5-level inverter with an output transformer for driving LSM. The control method is based on a space vector coordinate, and this is possible to suppress a zero-phase sequence harmonics. This paper describes the outline of the control method based on space vector coordinate, The control performance and characteristics of harmonics are also evaluated.
