CIRCUIT ARRANGEMENT FOR SWITCHING A CURRENT, AND METHOD FOR OPERATING A SEMICONDUCTOR CIRCUIT BREAKER |
摘要 |
A control voltage is generated at a control input of a semiconductor circuit breaker by an actuation circuit at switching flanks of a switching signal, said control voltage having a profile which is flattened in relation to the profile of the switching signal. With the disclosed method, the switching losses in a semiconductor circuit breaker are reduced. By defining a value for a switching parameter of a control device of the actuation circuit, the switching behavior of the actuation circuit can be influenced by the switching parameter. A specific parameter value of the switching parameter can be varied during operation of the actuation circuit. |
