This paper deals with a welding time for a spot welding system. Conventional welding machine adopts several tens of switching devices connected in parallel to obtain a short welding time. This paper analyzed a welding system consisting with 4 IGBT switchs for a full-bridge inverter and conventional 60 [Hz] transformer. The simulation and experimental results show that the welding time can be minimized to 5 [ms] with the proposed scheme.
