Inverter Output Voltage Synthesis Using Novel Dead Time Compensation

새로운 데드타임보상법을 이용한 인버터 출력전압의 합성

In is paper, a novel dead time compensation method is presented which produces inverter output voltages equal to reference voltages. An experimental result is also presented to demonstrate the validity of the proposed method. The reference voltage can be used as a feedback value, which is essential for sensorless vector control and flux estimation. The method can be carried out automatically by an inverter controller for initial set-up without any extra hardware.
