Abstract :
A phase-modular isolated three-phase AC/DC converter topology and its modulation and control scheme is proposed. The topology, denominated as IMY-Rectifier, is based on a star connection of single-phase mains frequency to high frequency AC/AC matrix converters at the input, feeding high-frequency isolation transformers. The transformer secondary windings are connected in series to the input of a diode rectifier with LC output filter. The converter provides a controlled output voltage and sinusoidal input currents in phase with the mains voltages. A description of the converter, its operating principle and an analytical calculation of the component stresses is presented.
