  1. In fact I am not sure you have understood me well. I will try to explain better the matter. I use the thyristors in series in order to have a greater rating, to have a greater voltage at the 2 terminals of my set of thyristors. For exemple, let us use 2 thyristors in series. If one of them turns on before the other, then a too great rating will be applied to the terminals of this thyristor, and it will be destroyed. This difference of time can be due to the different physical characteristics of the 2 thyristors. Let me explain. We have to apply a current on the gate of each of the thyristors
  2. Thank you, those who were kind to reply to my poll I use indeed the thyristors in series in order to increse the rating. Please, make for me a more detailed answer. Thank you in advance alex
  3. Please help me to solve a problem. I work to a project with power thyristors in serial connection. The problem is linked to the simultaneous turn of all the thyristors. If some of the thyristors are turned on before the other, then a very high voltage is applied to the terminals of one or more thyristor for a certain time interval, and this can provoke the destruction of the thyristor. The turn on of the thyristors is commanded by a gate current. All of the thyristors are of the same tyme but, of course, they are not perfectly identical: this is the problem because, the time interval of the a
