description	A switching power supply device (1, 1A, or 1B) includes a pair of input terminals (T1 and T2), a pair of output terminals (T3 and T4), N number (N: an integer of 2 or greater) of transformers (31 to 3n), N number of inverter circuits (2 (21 and 22) or 2B (21 to 2n)), a rectifying and smoothing circuit (4 or 4A), and a driver (5). The transformers (31 to 3n) include respective primary-side windings (311 to 3n1) and respective secondary-side windings(312 (312a and 312b) to 3n2). The inverter circuits (2 (21 and 22) or 2B (21 to 2n)) are disposed in parallel between the pair of input terminals (T1 and T2) and the primary-side windings (311 to 3nl) and each include switching elements (S1 to S4). The rectifying and smoothing circuit (4 or 4A) is disposed between the pair of output terminals (T3 and T4) and the secondary-side windings (312 (312a and 312b) to 3n2) and includes a rectifying circuit and a smoothing circuit. The driver (5) sets an input voltage (Vin) to be supplied to the smoothing circuit at successive stage levels (N + 1) by causing, through switching driving, the inverter circuits (2 (21 and 22) or 2B (21 to 2n)) to apply a predetermined pulse voltage or a voltage at a predetermined voltage value (Va or Vb) to the respective primary-side windings (311 to 3n1).
