Abstract :
This paper presents a new method to increase the magnitude of impulse square wave of Pulse Forming Grid (PFN) and capability of producing the repetitive impulse waves by temporary converting it to Boost Converter (BC). For achieving to this goal the PFN inductors and capacitors are connected in series and parallel respectively using solid state switches and during this procedure the PFN impulse generator converts to BC and increases the voltage of capacitors uniformly to the considerable value. This technique causes to increase the discharging voltage level to the load many times more than its DC voltage source without using additional converter or transformer. The yielding results from numeric simulations in MATLAB prove this technique.
