| Abstract: | The paper introduced a new three-phase thyristor rectify trigger circuit.The circuit was made up of microcomputer LPC2132,CPLD EPM570T1100C5 and other machines. Through using digital phase tracing technique and exceed zero trigger method, we can get different sequencable trigger pulse through changing software.The method can Synchro-nized trigger pulse and power signal accurately.It raised trigger's anti-interference ability and improved three-phase trigger pulse's Symmetry. |
