A high-current air-core pulse transformer has been designed and fabricated. Its purpose is to reduce the output impedance (nominally 100 milliOhm) of a 50-kJ, 1000-microF capacitor bank for application to loads with impedances of about 25 milliOhm. The system will be used for high current component testing, specifically experimental evaluation of the pressure limits of high-strength wrapped hypervelocity railgun sections. The transformer will be part of a test stand consisting of five capacitor bank/transformer sets capable of delivering up to 1.5 million. A to a load. The geometry of the transformer is coaxial. The secondary coil consists of circular aluminum . tubes connected in parallel. The primary winding is contained within the tubes and is connected in series. The coaxial geometry was chosen for its high coupling coefficient and its mechanical simplicity. Design improvements and future refinements are also discussed.
