Synchronous Boost DC-DC Converter for Nitrogen Plasma

Abstract

The paper describes a high power synchronous boost inverter for Nitrogen plasma torches. A high frequency was used in order to drive the pulse width modulation circuit. The average output current consumption (AOCC) was modified from (15A) up to (25A). The (AOCC) was reduced from (25A) down to (15A) by increasing the duty ratio from (0.75) up to (0.88). The switching frequency of the sync boost inverter was fixed at (20KHz).
