Abstract：During commutation in a variable polarity welding power supply with a reverse voltage stabilizer, the instantaneous pulse power loss loaded on the insulated gate bipolar translator (IGBT) could cause a jump in the junction temperature that might exceed the maximum allowable junction temperature, threatening safe operation of the IGBT. Formulas were derived to calculate the highest junction temperature using a partial fraction circuit model in the thermal-electric equivalent method. The results were compared with simulation results to verify the formulas. The effects of the main parameters on the junction temperature were analyzed to develop constraint conditions for controlling the IGBT junction temperature in a safe range. These results provide a theoretical basis for choosing reasonable IGBT and its working parameters for the power supply circuits and control strategy.
