Abstract :
This paper extends the limit-trajectory two-mode overmodulation ideal into single mode. The harmonic characteristics of them are analyzed and compared. Based on one TI TMS320LF 2407A DSP, the proposed method is verified with an open-loop V/F controlled diode-clamped three-level model inverter. With the test result, it is confirmed that single-mode limit-trajectory overmodulation technology is correct and effective
