1. A charging circuit for a frequency converter, comprising:
- a first feed line comprising a first constant current source therein;
a second feed line comprising a second constant current source therein;
an intermediate circuit capacitor connected between said first feed line and said second feed line, wherein said first constant current source that limits a charging current of said intermediate circuit capacitor; and
an electronic control device that controls both said first constant current source and said second constant current source in parallel.

Abstract
A charging circuit for a frequency converter having a first feed line with a first constant current source therein and a second feed line with a second constant current source therein. An intermediate circuit capacitor connected between the first feed line and the second feed line, wherein the first constant current source that limits a charging current of the intermediate circuit capacitor. An electronic control device that controls both the first constant current source and the second constant current source in parallel.
