Zusammenfassung:	To provide a pulse power supply device capable of exactly controlling a voltage value of a pulse voltage.SOLUTION: A first pulse voltage generation circuit includes a transistor Q5 (first switching element) and a transistor Q6 (second switching element) connected in series between a power supply voltage terminal Nv and a ground terminal GND to output a first pulse voltage from a first output node. A second switching circuit of a second pulse voltage generation circuit includes a transistor Q7 (third switching element) and a transistor Q8 (fourth switching element) connected between output terminals of a DC/DC converter 303 to output a second pulse formed by superimposing a first pulse voltage over an output voltage of the DC/DC converter 303 from the second pulse voltage as an offset. An electric charge absorber circuit DI, which is connected between the output terminals of the DC/DC converter 303 and can control an ohmic value, is connected.SELECTED DRAWING: Figure 2A 【課題】パルス電圧の電圧値を正確に制御することができるパルス電源装置を提供する。【解決手段】第１パルス電圧発生回路は、電源電圧端子Ｎｖと接地端子ＧＮＤとの間に直列に接続されるトランジスタＱ５（第１スイッチング素子）とトランジスタＱ６（第２スイッチング素子）とを備え、第１出力ノードから第１パルス電圧を出力する。第２パルス電圧発生回路の第２スイッチング回路は、ＤＣ／ＤＣコンバータ３０３の出力端子間に接続されるトランジスタＱ７（第３スイッチング素子）とトランジスタＱ８（第４スイッチング素子）とを備え、第２出力ノードからＤＣ／ＤＣコンバータ３０３の出力電圧に第１パルス電圧をオフセットとして重畳させた第２パルス電圧を出力する。ＤＣ／ＤＣコンバータ３０３の出力端子間に接続され、抵抗値を制御可能な電荷吸収回路ＤＩが接続される。【選択図】図２Ａ
