Fabrication and Practical Considerations of a Flyback Transformer for Use in High Pulsed-Power Applications

The design and use of the flyback converter topology in high voltage applications is common. Most often these systems are low power units such as that found in a television electron beam circuit. However, little is recorded in the literature on the design and use of this topology for high, pulsed-power applications. These pulsed circuits have a variety of end uses, including anti-terrorism. For example, work has recently been reported on the use of high-energy, pulsed power to destroy anthrax bacteria. This paper presents details on the design and fabrication of a high voltage flyback transformer for use in high, pulsed-power circuits. Experimental data from a 4.8 kW pulsed-power flyback converter is presented which documents the efficacy of the transformer construction
