Zusammenfassung:	To provide a high voltage DC voltage by reducing the number of semiconductor devices used to reduce conduction losses.SOLUTION: Diodes 12, 26, 34, whose number is larger than the number of transformers 6, 8 by one, are connected between secondary sides of transformers 6, 8 so that the secondary sides of transformers 6, 8 are connected in series when terminals 10, 28 on one of the secondary sides of the transformers 6, 8 of two power supplies 2, 4 have positive polarity. Diodes 18, 30, 32, whose number is larger than the number of transformers 6, 8 by one, are connected between secondary sides of transformers 6, 8 so that the secondary sides of transformers 6, 8 are connected in series when one side terminals 10, 28 on the secondary sides of the transformers 6, 8 have negative polarity.SELECTED DRAWING: Figure 1 【課題】高圧の直流電圧を、使用する半導体素子の数を少なくして導通損失を少なくして、得る。【解決手段】２つの電源２、４の変圧器６、８の２次側の一方の端子１０、２８が正極性のとき変圧器６、８の２次側を直列に接続するように、変圧器６、８の数より１だけ多い数のダイオード１２、２６、３４が変圧器６、８の２次側間に接続され、変圧器６、８の２次側の一方の端子１０、２８が負極性のとき変圧器６、８の２次側を直列に接続するように、変圧器６、８の数より１だけ多い数のダイオード１８、３０、３２が変圧器６、８の２次側間に接続されている。【選択図】図１
