| Abstract: | This paper analyzes the working principle of a half-bridge series resonant inverter by AC equivalent circuit of the inverter. The factors influencing the output power of the inverter are discussed. Then a ZX7-400S SCR inverter welding machine is devised. The design of this welding machine is reasonable. It has some properties of light weight, high efficency and low energy consumption. |
