Abstract: A multiple winding transformer includes a core unit, a first winding set which has N (N≥3) number of windings, and a second winding set which has at least one winding. The windings of the first winding set are overlappingly wound around the core unit. Each of the windings includes an input terminal and an output terminal. The input terminal of one of the windings is spaced apart from the input terminal of a next one of the windings by (360/N) degrees, and the input terminals are interconnected to form an input end. The output terminal of one of the windings is spaced apart from the output terminal of a next one of the windings by (360/N) degrees, and the output terminals are interconnected to form an output end.

Abstract: A power supply apparatus includes a switch, a converting module and a control module. When the switch operates in an ON state, an input voltage is outputted through the switch to serve as an output voltage. The converting module selectively converts the input voltage into the output voltage. When the power supply apparatus operates in a mode where the switch operates in an OFF state, where the converting module performs the conversion, and where the output voltage is stabilized at a target voltage value, and when a condition associated with the input voltage is met, the control module causes the output voltage to gradually change toward the input voltage.
