Abstract
A switching power supply apparatus includes: a pair of input terminals; a pair of output terminals; a transformer; an inverter circuit including first and second switching devices, first and second rectifying devices as voltage clamping devices, a resonant inductor, and a resonant capacitor; a rectifying and smoothing circuit; a current detector detecting whether a current is flowing through at least one of the first rectifying device or the second rectifying device; and a driver performing switching driving. The resonant capacitor is disposed between a second node and one of a pair of coupling lines. The driver performs switching driving to cause both the first and second switching devices to be set to an OFF state in a case where the current detector detects that a current is flowing through the at least one of the first rectifying device or the second rectifying device.
