METHOD AND CIRCUIT ARRANGEMENT FOR CHARGING AN INTERMEDIATE CIRCUIT CAPACITOR |
摘要 |
A method for charging an intermediate circuit capacitor in a precharging unit includes charging the intermediate circuit capacitor via a current source and adjusting the supplied current in such a manner that a constant power loss is produced in the current source during the entire charging operation. A circuit arrangement includes a battery which is connected to a current source which is connected to an intermediate circuit capacitor via a switch. An adjusting circuit is arranged in parallel with the current source and can be used to adjust the current for charging the intermediate circuit capacitor. The current is adjusted in such a manner that a constant power loss is produced in the current source during the entire charging operation.
