Abstract
The invention relates to a method for reducing the inrush current of an electrical device operated by means of a battery and/or an accumulator, which device is designed as a medical device which can be implanted in a patient and has an electronic circuit which is supplied with electrical energy via at least two supply potential lines, wherein the electronic circuit has a plurality of backup capacitors, each of which is connected or connectable by means of a first terminal to one of the at least two supply potential lines and by means of a second terminal to another of the at least two supply potential lines, wherein the electrical device has an energy management system by means of which one or more parts of the electronic circuit are switched off in an energy-saving mode and are switched on again when the energy-saving mode is exited, wherein the backup capacitors, individually or in a plurality of groups via one switching element per capacitor or group of capacitors, are disconnected from at least one of the supply potential lines in a switched-off state of the switching element and can be connected thereto in a switched-on state of the switching element, wherein the switching ele…
