Abstract: We have developed a high-frequency pulsed power generation system using either ten or twenty MOSFETs in series. The operation principle of the circuit was elucidated, and the experimental results confirmed the operation of the developed circuit. When twenty MOSFETs were used, repetitive operation was achieved at an output voltage of 10 kV and a frequency of 1 kHz. A preliminary experiment on underwater pulsed electrical discharge is performed, and the occurrence of underwater pulsed electric discharge was confirmed.
