摘要 |
Disclosed a switching power supply apparatus which includes a voltage converting transformer including an auxiliary winding on a primary side and a switching control circuit, wherein the switching control circuit includes a detection circuit to detect a falling edge of a terminal voltage of the auxiliary winding, and controls a switching transistor connected to a primary winding of the transformer based on the terminal voltage of the auxiliary winding at the time immediately before current flowing through a secondary rectifier diode of the switching power supply apparatus becomes zero, which terminal voltage is obtained based on a detection timing of the detection circuit. |
