摘要
A starting circuit for a single-phase AC motor, the single-phase AC motor comprising a main winding and a starting winding, and the starting circuit comprising a detecting circuit, a rectifying circuit, a triggering circuit, and a switch, wherein the detecting circuit is connected in series with the main winding, the switch is connected in series with the starting winding, the detecting circuit transfers current parameters of the main winding into detecting signals, the rectifying circuit processes the detecting signals and transmits the detecting signals to the triggering circuit, the triggering circuit controls the switch according to the detecting signals whereby controlling power-on and power-off of the starting winding, and the triggering circuit is a hysteresis comparing circuit.
