A pulsed power supply includes a DC power source, and a transformer and a switch which are connected in series with each other across the DC power source. The pulsed power supply operates to produce a plurality of high-voltage pulses in a repetition of cycles in each of which an induced energy is stored in the transformer when the switch is turned on and a high-voltage pulse is generated across a secondary winding of the transformer when the switch is turned off. The current flowing through the primary winding of the transformer is controlled to keep its peak value constant. The pulsed power supply further includes a current detector for detecting the current flowing through the primary winding of the transformer, and a third circuit for turning off the switch when the current detected by the current detector reaches the peak value.
