Abstract:
A circuit arrangement for limiting peak current, comprising:an inverter providing an AC voltage output, a series circuit comprising a consumer and input terminal of a rectifier unit connected across said output;a current limiter having first and second terminals connected across output terminals of the rectifier unit;a series circuit comprising a measuring shunt and a switching element being connected across the first and second terminals, a control input of the switching element connected to an output of a current regulator, a first input terminal of the current regulator connecting to one side of the measuring shunt and a second input terminal of the current regulator connecting to an opposite side of the measuring shunt; andthe current regulator controlling the switching element so that when a peak current flows through the switching element, a height of the peak current is limited to a desired maximum current value determined primarily only by a potential across said measuring shunt.
