In order to couple two networks, in particular the output voltages or currents of two out-of-phase, synchronized power converters, to a common three-phase network, an interphase reactor arrangement is provided with an interphase reactor coil (W1R, W3R) and an additional choke (W2R) for each phase of the common network. The additional choke (W2R) is coupled magnetically with the interphase reactor, but connected, by means of a series connection with another interphase reactor (W1T, W3T), to another phase output (T1, T2) of the two power converters. The magnetic core (MR) of the mutually coupled coils (W1R, W2R, W3R) is thus traversed by different phase currents from the power converters, which ensures a phase angle rotation between the output currents and voltages of the power converters to be coupled. Thus, for example, two 6-pulse power converters can be operated on one network and generate a 12-pulse mains current. |
