Popis: Five different types of pulse power capacitors, each with a different dielectric material, were evaluated in an underdamped circuit. The purpose of these measurements was to determine the applicability of the various capacitor technologies for use in circuits where severe ringing will be required. Such circuits could include induction type electromagnetic launchers. It was found that severe losses, due to the effective series resistance (ESR) of the capacitors, manifested themselves. This places severe restrictions on the application of such components to circuits that require highly efficient transfer of energy from energy storage to the load. The degree of the loss varies considerably from capacitor dielectric to dielectric and from electrode construction to electrode construction.
