3. Summary 

of 

Principle 

The invention of inverter arc welding benefits from appearance of the inverter theory 
and device. The inverter arc welding power source works rectifying 50/60HZ working 
frequency to direct current, inverting to HF by the high power switching device 
IGBT( the frequency can reach 20KHZ), then reduce voltage and rectification, output 
the dc high-power supply by PWM, the weight and volume of main transformer are 
remarkable decreased, and the efficiency is raised over 30%.
