SUMMARY This work focuses on the design of a compact high‐power pulsed electromagnetic wave generator using a nanosecond pulsed power generator for the cancer treatment. In the previous study, since the output voltage waveform of the pulsed power generator was damping oscillation, the duration of the burst pulse was under 100 ns. So the generator uses a magnetic switch instead of the gap switch and uses a SOS diode with current cutoff time of nanoseconds. The cluster pulse has six burst pulses that are repeated at 2 Mpps. The frequency of the burst pulse is 50 MHz. The peak output voltage is 7.5 kV.
