Design of a Single Chip PWM Driver Circuit for Inverter Welding Power Source

This brief presents a simple cost-effective design approach for an insulated gate bipolar junction transistor (IGBT) gate driver board used in manual metal arc constant current power source and manual metal inert gas welding constant voltage power source. In order, to design a universal IGBT driver board, an electrical model of the inverter welding power source is analyzed in this brief and an experimental prototype was developed and was put in rigorous use to test its durability. The proposed method is applied to an 18 kW inverter welding power source, and then the measurement results are analyzed. A cost benefit analysis was made to ascertain the techno-economic viability of the proposed driver.
