Abstract :
A novel design concept of an interphase reactor in a three-phase twelve-pulse thyristor rectifier is proposed for reducing supply current harmonics. This concept requires only an interphase reactor with a small inductance value, and requires no additional switching devices. As the inductance value is decreased, the supply current approaches a sinusoidal waveform, which is more sinusoidal than that of a 36-pulse thyristor rectifier. The basic principle of the proposed concept is discussed in detail, and confirmed by using digital computer simulation. Experimental results verify the effectiveness and practicability of the proposed design concept of the interphase reactor
