PPPS-2013: Nanosecond high-voltage pulse generator using a spiral blumlein for electromagnetic interference test

Summary form only given. Electromagnetic pulse (EMP) can be delivered to electronic equipment in two ways. One is through the application of radiated fields, and the other is through conduction along cables and wires. In this study, a high-voltage pulse generator using a spiral Blumlein Pulse Forming Line (PFL) was developed for the test of EMP effect by radiation and conduction. For the conduction test, a spiral strip Blumlein PFL with transformer oil is employed to generate high voltage (>300 kV) and long duration (50~ ns) pulse. The pulse shape of the experimental result matched well with computer simulation. High power ultrawide band pulse for the radiation test was generated by combining a tem horn antenna with the high voltage generator. The peak-to-peak value of electric field intensity of a radiated pulse is approximately 53 kV/m at a distance of 10 m away from the antenna. The pulse generation system will be used for the examination of effects of the electric fields and conducted pulse on the operation of electronic devices.
