A scheme of using memory logic to implement 18-pulse quasi-sine wave ASVG pulse generator hardware is proposed. The actual operation shows that the pulse generator realized by the scheme has the advantages of high precision, small phase noise and good reliability, and effectively solves the problem of poor reactive power control and poor three-phase symmetry of the new type of static var generator (ASVG) The problem has been applied in the industrialized ASVG. The key technology of the pulse generator lies in the high-stability, high-precision and phase-doubled frequency pulse source. The feasible scheme of the frequency-doubling pulse source is given in this paper. The high-precision digital pulse generator is also suitable for other GTO inverter devices
