- Abstract:
- In various industries as a solution to energy production for a short period of time in order to have a high instantanuse power pulsed sources are widely used. This resource is a relatively long period of energy stored in the energy storage element and then this energy in a short period of time the exhaust. Among the most important applications of these resources can be used in radar systems, linear accelerators, pulsed lasers, nuclear fusion, medical applications, etc. Among the most important targets are the following sources can be output pulse quality, reliability and longevity of these resources, efficiency and cost them. From the perspective of the quality of the output pulse, rise time and fall time pulse, low ripple pulse top level, low loss pulse amplitude and pulse similarity targets that are reviewed. For pulses with a pulse width of a few nanoseconds the problem having rise time and fall time low ratio to pulse width is. The Thesis examines the factors limiting rise time and fall time pulse has been paid and some type of structure that has been used for the removal of these restrictions have been brought.The Thesis for the appropriate rise time and fall time in output waveforms have been proposed as a circuit that uses it has been tried To switch on and off time using the diode in the reverse bias of the output pulse is removed. To simulate this circuit Capture CIS software is used to make more realistic models of the elements used. also tried to take into account the parasitic elements. The results of the simulation are shown at the end of the advantages and disadvantages of this circuit have been investigated
