What is a solid state soft starter?

2025-04-01
A solid state soft starter is an electronic device used to control the voltage applied to an AC motor during startup. By using thyristors (SCRs) or other semiconductor devices, soft starters limit the initial inrush current and reduce mechanical stress on the motor and connecting equipment. The main features of solid-state soft starters include: the soft starter takes up less space than traditional starting methods such as autotransformers. The advantages of solid state soft starters include: the motor voltage gradually increases over a predefined period of time. Customizable starting profiles: Users can adjust parameters such as ramp time and starting torque.
