2. Working Principle of Soft Starter
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 swings between maximum & minimum peak forming a complete 360° cycle, we can use the angle of firing pulse to switch on the thyristor for a specific duration and control the supplied voltage.The firing pulses can vary between 0° to 180°. The decrease in the angle of firing pulse increases the conduction period of thyristor, thus allowing high voltage through it.
