Title:
METHOD AND CIRCUIT ARRANGEMENT FOR LIMITING PEAK CURRENTS AND PITCH OF CURRENT FLANKS
Document Type and Number:
WIPO Patent Application WO/2013/131905
Kind Code:
A3
Abstract:
Method for limiting peak currents, particularly depending on a charge quantity provided by a voltage source, and the maximum pitch of the current flanks of an electric motor (11) for an electrohydraulic motor vehicle brake system, particularly a pump motor, controlled by means of pulse width modulation (PWM), wherein a change to an actual duty cycle (OUT3) of the PWM is made by a first duty cycle of the PWM on a second duty cycle at runtime, characterised in that the change takes place according to a positive or negative pitch value (SLP) calculated and/or changeable at runtime. The invention further describes an electronic circuit arrangement for the implementation of a method for limiting peak currents and the maximum pitch of current flanks.
