The invention relates to a converter (K) for controlling power flows between at least three power networks (QAC, QHV, QNV) having different operating voltages (UA, UB, UC). The converter comprises atleast three terminals (A, B, C), each of which is configured for electrically contacting one of the three power networks (QNV, QHV, QAC), and at least two converter cells (Z1, Z2), each having a transformer (T) having at least three transformer coils (W1,A, W1,B, W1,C, W2,A, W2,B, W2,C). At least one of the terminals (A, B, C) is connected to a series connection of converter cells (Z1, Z2), whereas at least one of the other terminals (A, B, C) is connected to parallel connection of converter cells (Z1, Z2) via a bidirectional serial line. 提供用于控制至少三个电流网络（Q，Q，Q）之间的功率流的变换器（K），所述电流网络具有不同的运行电压（U，U，U）。变换器包括：至少三个端子（A，B，C），所述端子分别被设立用于电接触所述三个电流网络（Q，Q，Q）之一；以及至少两个变换器单元（Z，Z，...），所述变换器单元分别具有变压器（T），所述变压器具有至少三个变压器线圈（W，W，W，W，W，W，...），其中所述端子（A，B，C）其中至少一个与变换器单元（Z，Z，...）的串联电路连接，而所述端子（A，B，C）其中至少另一个与变换器单元（Z，Z，...）的并联电路连接。
