Abstract
The switching power supply device includes switching circuits, a transformer, an LLC resonance circuit, a microcomputer and a frequency regulator that sets switching frequencies of the switching circuits and a current detection circuit that detects the current Ir. The microcomputer and the frequency regulator sweep a switching frequency, and set a switching frequency on the basis of times to start the dead times of the switching elements, the current Ir detected by the current detection circuit, and the threshold current Imin.
