A novel soft starter based on AT89C51 single-chip computer for asynchronous motor is presented in this paper. The hardware circuit configuration of the single-chip computer control system, software diagrams and the realization method are gived. Experimental results show that the proposed system can effectively deerease the stator starting current and start smoothly without impulse and oscillation. The soft stopping, energy-saving of light load and protection of motor can also be implemented .
