In this thesis, soft starter equipment realized by thyristors power transform circuit is studied. To improve equipment performance, we apply variable reactance technique to AC motor soft starter study. The high voltage AC working winding of reactance is in series with motor winding, while low voltage control winding and thyristors groupware with intelligent controller constitute close loop circuit. We adopt thyristor phase control voltage-regulator mode to control low voltage winding, then control the reactance of high voltage winding, and then arrive at the goal-control the current and voltage of motor AC to realize motor soft starting.
