The circuit generates the high voltage pulse by connecting the capacitors in parallel and connecting in the series of capacitors in the circuit. Normally ‘N’ number of capacitors are charged in parallel to the voltage (v) connected in series with the resistance Rc. In this operation the circuit acts as an open circuit when all the capacitors are charged. When the sparks gap uses a switch which has the voltage (v) across them, but these sparks gaps are having breakdown voltages greater than the normal voltages. To generate the output pulses at the first spark gap causes breakdown effectively to short the gap when placing the first two series applying a 2 volt placing the first two capacitors there in the series then applying voltage of the second spark gap consequently. The second gap is consequently add the third capacitor to stack and the process continues to break down all of the gaps. The last gap is connected to the output of the series stack of capacitors to the load circuit.
