A pulsed power supply device in which a capacitor (23) having a charged voltage is discharged quickly upon closure of a switch (24). First and second series circuits (51, 52) are connected to each other in series and provided between the output terminals of a DC voltage source (2). The first series circuit (51) is a series circuit of a first reactor (14) and a first forward-direction diode (15), and the second series circuit (52) is a series circuit of a second forward-direction diode (16) and a switch (24). A third series circuit (53) that is a series circuit of a capacitor (23), a second reactor (25), and a discharge tube (9) is connected in parallel to the second series circuit (52). Upon closure of the switch (24), the discharge tube emits light and, on the other hand, the capacitor (23) is discharged to produce an oscillation current, whereby a voltage develops across the capacitor (23) in the polarity opposite to the polarity at the time of the initial charging. Since this voltage is added to a power source voltage and reused in the next charging cycle, the pulsed power supply device has a high efficiency.
