Beschreibung
Zusammenfassung:	A DC-DC converter includes a DC-AC conversion circuit, a transformer, rectifier circuits, smoothing circuits, and an output circuit. The DC-AC conversion circuit converts a DC input voltage to a primary-side AC voltage. The transformer includes a primary-side coil to which the primary-side AC voltage is applied, and secondary-side coils magnetically coupled to the primary-side coil. The rectifier circuits are provided in one-to-one correspondence with the secondary-side coils. Each of the rectifier circuits outputs a rectification voltage resulting from full-wave rectification on the secondary-side AC voltage output from the corresponding secondary-side coil out of the secondary-side coils. The smoothing circuits are provided in one-to-one correspondence with the rectifier circuits. Each of the smoothing circuits smooths the rectification voltage output from the corresponding rectifier circuit out of the rectifier circuits. The output circuit is connected to respective output terminals of the smoothing circuits. The output circuit outputs a DC output voltage.
