Abstract
A frequency converter includes: at least one bridge arm, wherein a shunt resistor is arranged in the bridge arm; an evaluation device having an input connection, the evaluation device being designed to evaluate a measurement signal which is present at the input connection and which is dependent on a voltage drop across the shunt resistor, in order to determine a measured variable; and a voltage peak suppression device, which is designed to short-circuit the input connection of the evaluation device when a voltage peak occurs at the shunt resistor.
