A novel super low inductance primary ring utilized in a pulsed dual resonant tuned transformer

The Air Force Research Laboratory (AFRL) has developed a super low inductance primary (SLIP), dual resonant tuned transformer for ultra wide band impulse radiation applications. The design criteria and the theoretical formulation for such a device are presented. Transformers with sub-microHenry (/spl mu/H) inductance in the primary are achievable. The inductive loop of the primary incorporates the capacitive energy store and pulse power switch. Correspondingly, low inductance in the secondary winding is plausible, thus decreasing loss due to stray capacitance. Implementation of dual resonant tuning is more easily attained with this technique, permitting the pulse power system to occupy a smaller volume.
