Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A circuit arrangement for switching a current as a function of a predetermined switching signal, comprising: a semiconductor circuit breaker for switching the current, an actuation device configured to receive the switching signal and to generate at a control input of the semiconductor circuit breaker as a function of the received switching signal a control voltage having a temporal profile, wherein the temporal profile causes switching between a conductin…
