Abstract
A gate drive that uses forced commutation to switch on the main device is described. The fundamental limits of the drive are pointed out, including minimum off-time and maximum on-time. The results of a loss analysis performed on the drive are presented. Experimental results show that the efficiency of the drive is exceptionally high when compared to conventional gate drives, and measured turned-on times of a zero turn-off thyristor are extremely low.Keywords
