Abstract
In a circuit arrangement for limiting peak current, an inverter provides at an AC voltage output a series circuit of a consumer and a rectifier unit connected across the output. A current limiter connects across output terminals of the rectifier unit. The current limiter has first and second terminals, a series circuit formed of a measuring shunt and a switching element being connected across the first and second terminals. A control input of the switching element is connected to an output of a current regulator. First and second input terminals of the current regulator connect to both sides of the measuring shunt. The current regulator is designed to control a switching element such that when a current maximum representing a peak current flows, a height of the peak current is limited to a desired maximum current value determined primarily by a potential across said measuring shunt.
