alex_craiova Posted November 2, 2005 Report Share Posted November 2, 2005 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 application of the gate current in order to turn on the different thyristors is a little bit different from one thyristor to other. This little difference can provoke the destruction of certain thyristors by application of an overvoltage.Can anybody help me with this problem?Thank you in advance.Alex Quote Link to comment Share on other sites More sharing options...
