In the class of polyphase inverters three-phase inverters are by far the largest group. A very large number of inverters are used for adjustable speed motor drives. The typical inverter for this application is a hard-switched voltage source inverter producing pulse-width modulated PWM signals with a sinusoidal fundamental Holtz 1992 . Recently research has shown detrimental effects on the windings and the bearings resulting from unfiltered PWM waveforms and recommend the use of filters Cash and .
