Abstract :
On the basis of analyzing three-level inverter direct torque control principle (DTC) , a new synthesizing vectors PWM method of three-level DTC is presented, which can not only effectively control neutral- point voltage, but also restrain higher dv / dt of output voltage and improve three-level DTC output performance ,reduce torque ripple. Through theory analysis and experiment research, the author proves the method is very effective and right. Finally, better result is achieved on a three-level sample inverter developed with TMS320LF2407A DSP.
