Abstract :
A current-controlled high power MOSFET switch for pulsing a hollow cathode discharge is presented. Dual current settings are provided, a low current for DC standby operation and a higher main discharge current. The performance of the switch was evaluated for both resistive and discharge loads. Limitations of other switching techniques are discussed
