Abstract
A dead band compensation system is provided that provides dead time compensation for a three-phase inverter in connection with counting the time difference between a pulse width without a dead time interval and a pulse width available at the output of the inverter (). An error measurement is determined, a portion of which is fed back subsequently. Harmonic components, among other things, are reduced, to an extent, in the load current through an inverter load (). Further, compensation for inverter voltage output errors may be provided.
