In a three phase induction motor, two SCRs are connected in an anti-parallel configuration along each phase of the motor making it a total of 6 SCRs. These SCRs are controlled using a separate logic circuitry that can be a PID controller or a microcontroller. The logic circuitry is powered from the mains using a rectifier circuitas shown in the fig... See more
The main component used for controlling the voltage in a soft starter is a thyristor. It is a controlled rectifier that starts conduction of the current flow in only One Direction when a gate pulse is applied called the firing pulse. The angle of the firing pulse determine how much of the input voltage cycle should be allowed through it. Since AC s... See more
Motor soft starter - Wikipedia
A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the powertrain and electric current surge of the motor during start-up. This reduces the mechanical stress on the motor and shaft, as well as the electrodynamic stresses on the attached power cables and electrical distribution network, extending the lifespan of the system.
