Abstract
A method, circuit configuration and bridge circuit for charging a capacitance effective on the main current terminals of a semiconductor switch, in particular an intrinsic capacitance, in particular the drain-source capacitance of a MOSFET semiconductor switch or the collector-emitter capacitance of an IGBT semiconductor switch, the precharging, in particular the at least partial charging, of the effective capacitance being forcibly controlled via a charging current path.
