This paper presents an adaptive dead-time compensation of voltage source inverter for variable speed drives. An evaluation index is developed to determine the magnitude of dead-time compensation voltage on-line. The evaluation index offers exact and quick identification. Furthermore, motor parameters are never used in this method. Experimental results verify that the distortions of phase current and commanded voltage are suppressed by applying the proposed dead-time compensation strategy.
