The Ultrafast capacitor bank designed, built, and tested by the Center for Design and Manufacturing Excellence consists of the energy storage/delivery system, the programmable logic controller (PLC), and the human machine interface (HMI) systems.

The design of the capacitor bank makes for a compact system with a very fast rise time. The system is a pulse power supply suitable for use with a variety of impulse-based forming and joining technologies, such as vaporizing foil actuator welding, electromagnetic and electrohydraulic forming. These technologies are fast and efficient methods of joining, forming and shearing.
