Abstract

In this paper the digital pulsed power system to supply a very small repetitive Mather-type Plasma Focus Device 20 J is presented The structure of this electrical system included a pulsed power supply and a Microcontroller based control system In Plasma Focus Devices a dc power supply charges a high voltage capacitor and then this saved energy discharges between two coaxial electrodes using a controllable spark gap switch The procedure of control the capacitor charging and discharging are explained in this paper Finally the experimental results of electrical discharge and pinch shaping in plasma focus in different working conditions are presented and a good repetitive performance in a wide domain of working conditions is seen
