dc.description.abstractTHE GENERATION OF COLD PLASMA IS APPLIED TO DIFFERENT PROCESSES AS GRINDING OF ROCKS, HARDENING OF METALS AND STERILIZATION OF FOOD. TO OBTAIN COLD PLASMA IN A VACUUM CHAMBER, IT IS NECESSARY TO PARTIALLY IONIZE THE GAS BETWEEN THE ELECTRODES, GENERATING HIGH VOLTAGE PULSES OF THE ORDER OF MICROSECONDS. THE REPETITION FREQUENCIES OF THESE PULSES DEPEND ON THE SPECIFIC APPLICATION. THE DESIGN OF THE POWER SOURCES CAN INCLUDE A SYNTHETIC PULSE FORMATION LINE (PFN) TRIGGERED OR USING VACUUM VALVES OR STATIC CONVERTER ARRAYS. IN LABORATORY APPLICATIONS WHERE APPLICATIONS FOR COLD PLASMA ARE STUDIED, IT IS CONVENIENT TO DESIGN A POWER SOURCE THAT CAN PROVIDE DIFFERENT LEVELS OF VOLTAGE AND CURRENT, WITH DIFFERENT PULSE WIDTHS, REPETITION FREQUENCIES, AS WELL AS SYSTEMS FOR PLASMA CHARACTERIZATION, AND AUTOMATION. OF EQUIPMENT OPERATING PROCEDURES FOR SAFETY. THIS WORK PRESENTS THE DESIGN OF A PULSATING SOURCE AND ITS ATTACHED SYSTEMS USING LOWCOST COMPONENTS, CONTRASTING THE THEORETICAL RESULTS WITH EXPERIMENTAL RESULTS.
