Zusammenfassung:	A switching power supply device is provided with: an input terminal pair; a pair of output terminals; N transformers each having a primary winding and a secondary winding, N being an integer of 2 or more; N inverter circuits which are connected in parallel between the input terminal pair and the primary winding, and each of which is configured so as to include a switching element; a rectifying andsmoothing circuit disposed between the pair of output terminals and the secondary winding, the rectifying and smoothing circuit being configured so as to include a rectifying circuit having a plurality of rectifying elements and a smoothing circuit having a choke coil and a capacitor element disposed between the pair of output terminals; and a drive unit for performing switching drive for controlling the operation of each of the switching elements of the N inverter circuits. The drive unit performs switching drive such that a predetermined pulse voltage or a predetermined voltage is applied to the primary windings of
