Abstract
A small-sized pulsed power supply unit capable of being manufactured at low cost. A switch (4) is connected in parallel to a capacitor (5) and a discharge load (6) in such a manner that it forms a closed circuit together with a DC voltage source (1) and a reactor (2) when the switch (4) is turned on, so as to store electromagnetic energy in the reactor (2), and a closed circuit together with the reactor (2), the capacitor (5) and the discharge load (6) when the switch (4) is turned off, so as to charge the electromagnetic energy stored in the reactor (2) to the capacitor (5) as electrostatic energy at a charge voltage higher than an output DC voltage of the DC voltage source (1). A voltage detector (7) detects the voltage of the DC voltage source (1), and a current detector (8) detects a current flowing through the reactor (2). A control circuit (9A) switches on and off the switch (4) based on the detected voltage and the detected current.
