ABSTRACT:
A digital phase-shifting circuit employed for a thyristor converter, which operates on a polyphase power supply. In the digital phase-shifting circuit which is simply constructed as a whole, a counter portion consists of an N-bit binary counter and a divide-by-six ring counter, and a comparator portion consists of a common comparator which compares data bits and simply constructed two-bit comparators that are provided for each of the phases.
