- Pulsed power
Pulsed power is the term used to describe the science and technology of accumulating
energy over a relatively long period of time and releasing it very quickly thus increasing the instantaneous power.Overview
Steady accumulation of energy followed by its rapid release can result in the delivery of a larger amount of instantaneous power over a shorter period of time (although the total energy is the same). Energy is typically stored within
electrostatic field s (capacitor s),magnetic field s (inductor ), as mechanical energy (using largeflywheel s connected to special purpose high currentalternator s), or as chemical energy (high-current lead-acid batteries, orexplosives ). By releasing the stored energy over a very short interval (a process that is called energy compression), a huge amount of peak power can be delivered to a load. For example, if onejoule of energy is stored within a capacitor and then evenly released to a load over one second, the peak power delivered to the load would only be 1 watt. However, if all of the stored energy was released within onemicrosecond , the peak power would be onemegawatt , a million times greater. Examples where pulsed power technology is commonly used includeradar ,particle accelerator s, ultrastrongmagnetic field s, fusion research,electromagnetic pulse s, and high power pulsedlaser s.History
Pulsed Power was first developed during
World War II for use inRadar . A massive development program, similar in scale to theManhattan Project , was undertaken to develop radar. Radar requires short high power pulses. After the war development continued in other applications leading to the super pulsed power machines atSandia National Laboratories .Manufacturer
