Repetitive pulsed power system has been developed to be used for repetitive applications. Furthermore, necessary of applications are fast charging a capacitor and high stability. We have studied and developed a capacitor charger for repetitive and compact pulsed power generator. Input voltage is 100V AC. The structure consists of converter, inverter, step-up transformer and control circuit. This power supply rectifies the incoming plug in AC power, generate a high frequency AC waveform through the operation of a series resonant inverter, and finally transform and rectify the high frequency AC waveform to the desired output. The inverter operates at approximately 1MHz.
