to 100000 times.
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.
