Energy compression and transfer using hybrid pulsed power transformer (HPPT)

Hilal, M.A. / Leung, E.M.W.

The historical approach to energy compression for Space Defense Initiative (SDI) applications has been to use a storage-inductor/homopolar-generator combination to transfer power from the primary energy source to the load. An innovative transformer concept, the hybrid pulse power transformer (HPPT), replaces the inductor and the homopolar generator. This pulse transformer significantly increases the energy transfer efficiency and eliminates the need for a high-current switch. It requires the use of a superconducting primary with a composite conduction that becomes highly resistive when driven normal. The sequence of HPPT operation is to charge the superconducting primary, then drive it normal when the energy pulse is required. The primary total resistance determines the time constant of energy transfer independently of its distribution. Since the winding resistance and inductance are distributed along the windings, internal voltage elimination is achieved locally. A 100 mJ HPPT system is described along with its performance characteristics. Experimental results for a small HPPT model which was constructed for the purpose of verifying the HPPT concept are given.
