Title:
METHOD AND DEVICE FOR PRECHARGING AN ELECTRICAL LOAD
Document Type and Number:
WIPO Patent Application WO/2013/113601
Kind Code:
A3
Abstract:
The present invention relates to a method for precharging an electrical load (40) which is connected to an electric network, especially a high-voltage network, supplied by a battery (100) and which is precharged via a first precharge resistor (12) by means of a starting current (UK1) present in the electric network. An additional precharge resistor (13, 14) or a plurality of additional precharge resistors (13, 14) are additionally connected in parallel to the first precharge current (12) in such a manner, especially in series, such that a predetermined precharge voltage having a predefined time behavior (UK3) and a correspondingly predetermined starting current (IK) for precharging the electrical load (40) during the starting process are generated during the starting process.
