Abstract: To develop a light and small high voltage pulsed power source, an innovative fast pulse technology based on an explosive driven ferroelectric generator (EDFEG) is investigated. An EDFEG is used as the primary power supply, inductive energy storage technology and an electrical exploding opening switch (EEOS) are used to generate a high-voltage fast pulse. On the basis of full-circuit simulation model of EDFEGs and the material properties of ferroelectric ceramics, the circuit simulation research on this fast pulse technology is carried out. The simulation results reveal the influence of circuit parameters on high voltage pulse generation. The research shows that the high-voltage mode of EDFEGs is more suitable for generating high-voltage fast pulse combined with EEOS technology. As a result, the principle of this technology is verified in experiments. In the experiment, the output current of an EDFEG was about 360 A and its pulse width was about 3.8 μs. The charging voltage of a 17.5 nF capacitor was 75 kV. After the capacitor was discharged, a pulse current with a peak value greater than 12 kA was generated in an EEOS. Finally, a high-voltage fast pulse with a voltage peak value greater than 180 kV, a rise time of 3 ns, a pulse width of 30 ns and a current peak of 3.4 kA was obtained on an X-ray diode load.
