Abstract
A start circuit for a single-phase AC motor controls the current through the start or auxiliary winding based on time rate of change of voltage or current, or based on the current or voltage dropping or rising some fraction from inrush value, i.e., to 50% of initial start current or to 150% of initial start voltage. The circuit can also include a default timer to time out the start current after some preset period between 300 and 1000 milliseconds.
