Abstract
Opening switches are critical components for inductive storage systems and also find applications in pulse compression and power distribution systems. Inductive storage systems are very attractive because the stored energy density is orders of magnitude larger than can be stored in capacitors. This chapter shows a typical schematic of an inductive energy storage device. The key to unlocking the potential of inductive energy storage is the opening switch, and numerous opening switch concepts have been proposed for singleshot operation. Repetitive operation of opening switches would impose additional design requirements for efficient heat removal. The chapter discusses the basic concepts and principal features of various opening switch configurations. The overall efficiency of an opening switch in an inductive energy storage system is determined by conduction time and opening time of the switch, the trigger sources for opening and closing the switch, and the rate at which the dielectric recovers its electrical strength.
