Beschreibung
Zusammenfassung:	A power supply device includes a transformer, a rectification smoothing circuit having positive and negative output ends that rectifies and smoothes an induced voltage at a secondary winding of the transformer so as to generate a direct current voltage between positive and negative output terminals, a serial connection terminal to which another power supply device is connectable and is connected to the positive output end, the negative output terminal is connected to the negative output end, the reverse flow prevention rectifying device is connected between the positive output end and the positive output terminal, its forward direction faces toward the positive output terminal, and the bypass rectifying device is connected between the positive output end and the negative output end, its forward direction faces toward the positive output end. Therefore, a plurality of power supply devices are easily connected in series without providing external diodes for each power supply device.
