A cycloconvertor (SC) transmits power between a three-phase network (N1) and a single-phase network (N2) with a lower operating frequency than that of the three-phase network. The cycloconvertor is of two-phase design on the secondary side, that is, generates a two-phase alternating voltage system on its terminals (A, B, NP) facing the single-phase network. The single-phase network is connected to two of these terminals. Between these two terminals (A, B) and the third terminal (NP), controllable reactive power members (TAC, LAC; TBC, LBC1, CBC, LBC2) are connected. A control device (CD) is adapted to control the reactive power members for symmetrization of the load of the cycloconvertor. |
