Pulsed Power For Repetitively Pulsed High-Power Discharge Lasers
SPIE Proceedings, 1987For modulators driving high-power discharge lasers, themajor system issues are system performance, efficiency, output voltage and risetime, and required electrical output characteristics dictated by the design of the laser cavity. From the system issues, modulator trade-offs are determined; these design trade-offs include shape of the output waveform ...

Pulsed power refers to the science and technology of accumulating energy over a relatively long period of time and releasing it as a high-power pulse composed of high voltage and current over a short period of time; as such, it has extremely high power but moderately low energy.

Pulsed power for EMP simulators
IEEE Transactions on Antennas and Propagation, 1978Simulation of nuclear weapons effects has been the main motivation for pulse power development in the U.S. in the last decade. EMP simulation has been responsible for a major class of pulse power systems. A general survey of pulse power techniques is given, focusing of those particularly applicable for EMP simulation.

Pulsed power diagnostics for power IGBTS
2009 IEEE International Conference on Plasma Science - Abstracts, 2009The power insulated gate bipolar transistor (IGBT) is used in many applications. While the use of the power IGBT is well characterized for many continuous operation power electronics applications, little published information is available regarding the performance of a given IGBT for pulsed power applications.

Pulsed power generators are capable of delivering as much as megajoules of energy in pulses of 100 nsec or less. A brief review of the technological approach to this problem is presented as well as the description of three different devices: Gamble II, AURORA, and a small laboratory device designed at NRL.

A power supply for pulsed power welding
IEEE Spectrum, 1968The use of pulsing current for gas-metal-arc welding has increased the versatility of the method because of the ease of varying the average current to suit the application. A power supply consists of two properly designed constant-potential power sources in parallel to provide two levels of current.

2019 IEEE Pulsed Power & Plasma Science (PPPS), 2019
This article is a continuation of the research of Pulse Power Systems [1], [2]. Current features as well as complications of Electromagnetic Launchers (EL) of projectile are well known. The low efficiency of EL prompted the research for a fundamentally new type of devices, as well as a new type of electromagnetic energy sources.
