In order to reduce the rush-current’ s impacts on the electromotor and electric network, we developed a kind of voltage-tuning motor soft starter controlled by monolithic-microcomputer. In this paper, the principle of work, the major of function, the design of hardware and software, and controlling algorilhm are presented. The results of simulation and application verified the effectiveness of the starter.
