This book presents a new inverter phase-leg configuration that is inherently immune to shoot- through failures, eliminating one of the most serious failure modes in the conventional phase-leg configuration. The augmented phase-leg configuration (APLC) requires a single command signal and a simplified gate drive configuration to control the phase leg operation. The APLC also provides a significant advantage of eliminating the need for introducing dead-time intervals in the control of standard inverter phase legs. Very low levels of both harmonic distortion and nonlinearity are demonstrated using this new phase-leg configuration, making it attractive for many motor drive applications including low-frequency sensorless vector control, flux estimation, and open- loop voltage control. An alternative APLC topology is presented using a synchronous rectifier MOSFET that offers reduced losses by decreasing the forward conduction drop of the series diode. The results of this...
