ABSTRACT:
A pulse electric power unit according to this invention performs a switching control of output current from a direct current power supply by means of an electronically-operated switch to thereby effect a voltage conversion for producing a voltage having the polarity opposite to that of a direct current voltage by causing a direct current voltage of the direct current power supply to vary, or producing a voltage having the same polarity as that of the direct current voltage by boosting and/or unboosting the direct current voltage or producing a voltage having the same polarity as that of the direct current voltage by boosting the direct current voltage. This pulse electric power unit can prevent improper current from occurring by means of a reverse-current blocking diode for blocking a capacitor from being discharged and can output pulse current having a quick rise/fall characteristic.
