8098 Single-chip Computer Controller for Resistance Spot Welding Inverter

A system controlled by 8098 single-chip computer for resistance spot welding inverter is introduced.The hardware,software and function of the system are provided.Two PWM signals with 180 0 phase difference,which are used to control current of the inverter,are output by the computer.Current step-up control of the inverter is also obtained by the system.The control flexbility of the system is evident,which enlarges the utilization of the resistance spot welding inverter.
