Power management circuit for a magnetic repulsion punch.

摘要

A power management circuit for operating a magnetic repulsion punch comprising a storage capacitor 20 arranged to be connected in parallel with an inductive load 30 serving as an operating coil of the magnetic repulsion punch, a means 240, 440 for selectively and temporarily coupling the inductive load to the storage capacitor for forming a resonant circuit, and a means 100 for charging the storage capacitor after each operation.
