Multiple Coil Architecture for Inductive Pulsed Power Supplies

The use of electrical energy in modern launch systems has attracted considerable attention, particularly within the military sector, due to its numerous advantages in terms of performance, price, and safety. However, electrical launch systems require a power supply capable of delivering significant pulse currents. Two commonly used techniques in these systems are “XRAM” and “Meatgrinder” (MG). This research presents a novel and enhanced architecture that incorporates multiple coupled coils in a single MG circuit, where the secondary coils are arranged in parallel using an XRAM approach with minimal switches used. The proposed architecture is described through mathematical modeling and further validated through numerical simulations and experimental unit testing. The results highlight the effectiveness and potential of the proposed architecture in improving the performance of pulsed power supplies.
