| Description: |
International audience ; This paper presents a modular and indigenous design of a 400 A / 120 V power supply for a plasma torch. The design employs three LLC resonant converters operating in parallel to power the plasma torch. The proposed design results in reduced electromagnetic component size, and offers convenience in fabrication, testing, and maintenance. Detailed calculations, simulation validation, and fabrication of a single 135 A / 120 V LLC converter module are evaluated and presented. The main features include the surge repression circuit, soft-switching for high efficiency, and dynamic response of the supply. The proposed system demonstrates practicality for highcurrent application in resource-constraint environments. |
