Alternating current soft start circuit

Abstract

An alternating current soft starting circuit comprising a power level detecting circuit responsive in an alternating current source and positioned to detect voltage changes by sensing frequency changes and voltage null points; and a micro-controller responsive to the power level detection circuit to monitor low power conditions and high power conditions to limit inrush current during high power condition from the alternating current source and to slowly ramp up to high power on-state condition.
