| Abstract: | The article introduces a Soft Starter with AT89C51 Single chip as key controller, using double-action silicon-controlled zero-passage trigger PWM technology, which enables voltage-regulation control. This can not only allow the control of motor start-up electric current using soft starter, but also overcome the disadvantage of normal soft starter that usually tends to bring harmonic wave pollution. Therefore, the starter has a great value in the application and promotion. |

| Keywords: | soft starter phase-shift trigger harmonic wave pollution zero-passage trigger PWM technology |
