The AC-to-DC single-phase PWM rectifier for traction applications using high POWE semiconductor, IGCT is made and tested. Parallel operation of two PWM converter is adopted of increasing capacity of converters For reducing harmonics, the harmonic content is eliminated by th phase shift between two converters switching phase The output voltage control is achieved by intern. calculation without detecting the input current. The part of PLL used for controlling power factor i, simply implemented by software.
