| Abstract |
A driver circuit for GTO-thyristors applied to power converters for railway vehicles is presented. The driver studied and the realized prototype concern power GTOs (about 4500V - 3000A). The driver circuit is made up of a signal part that generates output logical signals on the basis of other input signals and a power part directly connected to the GTO. The power part is realized with DMOS mosfets rather than BJTs to give easier driving and higher commutation speed. The gate behaviour of the GTO and the behaviour of the driver are studied and outlined. Some simulations of the power circuit of the driver were done and the results are discussed and compared with the experimental ones. |
