| Abstract |
The paper considers three common snubber circuits used on gate turn-off thyristor inverters. Each circuit incorporates both tum-on and turn-off snubbering action. The first snubber, which has resistive losses, is converted into an active recovery snubber with the addition of a switch. The remaining two snubbers to be considered are passive lossless circuits, and improvements and modifications to these are considered. The comparative features and operation of the three improved recovery snubbers are considered and supported by PSpice simulations and experimental results. |
