Summary:The method of a digital thyristor trigger control system of Three-phase AC voltage-regulating circuit on the base of singlechip controller is proposed. Automatic judgments of electric power phase sequence were designed in software. The working principle for phase-shifting triggering were mainly analysed. And the relationship for allotting pulses method were analysed. The programs of digital thyristor trigger control system were designed by MPLAB. And it were proved absolutely correctly by simulation model which was established by PROTEUS. Simulation results show that the digital thyristor trigger control system provides good performance. This system included controller and trigger, so as to reduce the component, reduce the cost and were more integrated, more precise.
