| Abstract: | Aiming at the defects of the traditional circuit the method for the digital phase-shifted trigger in three-phase circuit is proposed on the basis of CPLD.The circuit works around the programmable logic device,and it is designed on one chip so that it is stable with strong anti-jamming capability and produces highly symmetrical,quickly responsive and highly accurate trigger pulses,avoiding the defects of the traditional circuit. |
