Abstract

In this paper, a novel dead time compensation method is presented that produces inverter output voltages equal to reference voltages. An experimental result is also presented to demonstrate the validity of the proposed method. It shows that the compensation of the dead time is possible up to a sub-microsecond range. Also, the reference voltage can be used as a feedback value, which is essential for sensorless vector control and flux estimation. The method is based on space vector pulsewidth modulation (PWM) strategy and it can be carried out automatically by an inverter controller for initial setup without any extra hardware
