The phase-shifting control method is used in this system to realize digital trigger unit.Firstly,the synchronous circuit supplies the natural phase-converting point of thyristor’s voltage,which is used as the computation start point of phase-shifting pilot angle α.Secondly,according to the phase-shifting control voltage UK ,The timing constant is computed.Then,the circuit identifies the phase and selects thyristor according to the code reflecting the power supply’s state.The trigger pulse will be sent to corresponding thyristor at the setting time.If the control voltage UK is changed,the timing constant will be changed,which is the method to realize phase-shifting.
