  • Power converter circuit arrangement having a plurality of parallel power converters or power converter arms and balancing inductors connected in between
    Patent number: 5862047
    Abstract: A power converter circuit arrangement having a plurality of parallel power converters or power converter arms is specified, in which an effective uniform distribution of current can be achieved in a simple manner. This is achieved by virtue of the fact that balancing inductors which are arranged between two adjacent power converters comprise at least one ring core, and that the load connections of two adjacent power converters or power converter arms are looped through the ring cores from different sides and are brought together to a common load current connection of all of the parallel power converters or power converter arms.
