Abstract
A power electronic circuit arrangement includes functional blocks for controllable, bidirectional energy exchange between a rotating field machine with at least one phase winding and an external energy store with one positive terminal and one negative terminal. At least one functional block is designed as a functional block that is connection-compatible on the power side and includes at least one internal energy store, such that this functional block has at least one additional switching state, in which an output voltage (U) is more positive than the positive terminal (P) of the external energy store, and/or in which an output voltage (U) is more negative than the negative terminal (N) of the external energy store.
