    AC/DC Soft Starter

    Inrush current/Switch-ON surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Inrush current is much higher than the load’s steady-state current and that’s the source of many problems such as fuse blowing up, load failure, load’s lifetime...

    Hello Forum members, I am implementing a slow starter circuit for AC inductive loads. For this, I am using a Zero Crossing Detection scheme with a Pic 16f887.
