An intermediate circuit system comprises a first capacitor system (102) between a first pole (105) and a second pole (106), a second capacitor system (103) between a third pole (107) and the second pole, and a coupling circuit (104) between the first and third poles. The coupling circuit comprises an inductive element (108), a controllable switch (109) between a first end of the inductive element and the first pole, and another controllable switch (110) between the second end of the inductive element and the third pole. The coupling circuit further comprises a switching component (111) for conducting current from the second pole to the first end of the inductive element and another switching component (112) for conducting current from the second pole to the second end of the inductive element. Thus, the coupling circuit is capable of acting as a chopper circuit between the first and second capacitor systems. The figure proposed to be presented with the abstract: Figure 1 b. |
