摘要： The invention relates to a control transformer, designed as a phase-shifting transformer, wherein semiconductor switching elements are provided for each phase on a control winding (2, W1, W2, W3) having a plurality of partial windings (W1, W2, W3). According to the invention, in each phase (U, V, W) an additional connecting line (L1, L2) with an additional switching element (S1, S2) is provided, wherein each of said connecting lines connects a module (M3) of the respective phase to the end of the main winding (2) of the adjacent phase.
