To provide a power supply device capable of changing a terminal address and a control method.SOLUTION: The present invention relates to a power supply device 1 by which an input voltage Vin inputted to input terminals Vin(+) and Vin(-) is converted and outputted from output terminals Vout(+) and Vout(-). The power supply device 1 comprises: communication terminals SCL and SDA which communicate with each other in the case where the other power supply device of the same type as the power supply device 1 is connected in parallel; address setting terminals ADDR0 and ADDR1 in which address setting resistors R0 and R1 are connected with a ground line; and a control unit 10 which includes a plurality of control means of different control methods, to which a terminal address is set in accordance with resistance values of the address setting resistors R0 and R1, and which performs voltage conversion control in accordance with a control method which is selected in accordance with the terminal address.SELECTED DRAWING: Figure 1 【課題】端末アドレス及び制御方式を変更可能な電源装置を提供する。【解決手段】入力端子Ｖｉｎ(＋)・Ｖｉｎ(−)に入力された入力電圧Ｖｉｎを変換して出力端子Ｖｏｕｔ(＋)・Ｖｏｕｔ(−)から出力する電源装置１であって、電源装置１と同種の他の電源装置が並列接続される場合に相互に通信を行う通信端子ＳＣＬ・ＳＤＡと、接地ラインとの間にアドレス設定抵抗Ｒ０・Ｒ１が接続されるアドレス設定端子ＡＤＤＲ０・ＡＤＤＲ１と、制御方式が異なる複数の制御手段を含み、アドレス設定抵抗Ｒ０・Ｒ１の抵抗値に応じて端末アドレスが設定されると共に、端末アドレスに応じて選択される制御方式により電圧変換制御を行う制御部１０と、を備える電源装置１。【選択図】図１
