A novel injection scheme to improve the input current harmonics of a hybrid 12-pulse line-interphase-transformer rectifier with controlled output voltage by a two-switch boost-type output stage is presented in this paper. A theoretical derivation of the modulation for achieving purely sinusoidal input currents is introduced. Finally, the proposed scheme is analyzed and verified by numerical simulations and experimental results.
