Abstract
The lack of turn-off ability makes the spark gap-based Marx generator uncontrollable in terminating the output pulse. In addition, there are some limitations for rise time and voltage gain improvements in the conventional critically-damped Marx design. In this paper, an efficient over-damped design of Marx circuit is proposed, which leads to a shorter rise time as well as a larger voltage gain. A chopping magnetic switch is employed to achieve the desired values of the fall time and full width at half maximum (FWHM). Moreover, adding a DC bias circuit to the magnetic switch provides the ability to adjust the pulse FWHM parameter. Therefore, an output pulse with a shorter rise time, larger...

Abstract
In this thesis, marx pulsed power generators are investigated. Due to very large magnitude of its output voltage and very fast rise time, Marx generator is the first choice in lots of pulsed power applications. A significant barrier in the implementation of this generators are the switches with witch the structure is made. The short magnitude nominal voltage and current of the solid state switches lead to use of Spark Gaps in which the determinative parameter of the switch to turn on, is its breakdown voltage. These switches have some limitations in repetition rate and turn off ability. However due to very high range of nominal voltage and currents, they are an appropriate choice for marx...
