A detailed design and testing of a pulsed power system (PPS) which has been developed in order to drive a table-top inertial electrostatic confinement (IEC) fusion device are presented over here. A 0.04 µF, 100 kV capacitor has been used to store the energy for generating the pulse. Along with the capacitor, other critical components such as high-voltage spark gap switch, high-voltage power supply, high power resistors, and diodes, triggering unit have been combined to develop the PPS. The discharge current and voltage pulse have been recorded by using high voltage and current probes, respectively. A current peak of 
17.5 A at an input potential of − 70 kV and a power dissipation peak of 1200 kW have been observed when the spherical IEC fusion device is used as the load in the PPS.
