Abstract

A method for operating an electrical circuit is described herein. The circuit includes a power converter having a plurality of switches and two capacitors that are parallel to the switches. The plurality of switches and the two capacitors are connected in series. The power converter has two AC voltage-sided connections and a measuring resistor is connected to the ground. A ground fault is detected by measuring a voltage drop in a measuring resistor.
