Abstract
A switching regulation circuit for a dual-winding motor apparatus is provided. The switching regulation circuit comprises a gate-controlled device and a driving circuit. When one of the two windings generates an induced voltage signal greater than a threshold value, the driving circuit generates an output signal for turning on the gate-controlled transistor. Thereby, a parasitic diode of the gate-controlled device will not be turned on and damage the entire circuit.
