Soft starters are power electronics topologies allowing soft start/stop of induction motors widely used in industrial applications (i.e. water treatment). A model of a thyristor-based soft start of a 15kW induction motor is introduced (Simscape Electrical). The model provides both open-loop and closed-loop algorithms for thyristor firing (speed control with smooth bypass connection).
