Research Of Power Supply Of Endless Rolling Welding Machine

In the metallurgy field, the flash welding technology is introduced in the endless-rolling process. But the welding machine power supply is very important to the flash welding. It is necessary to study the welding machine power supply for endless-rolling. It can assure the working reliability of welding machine, decrease the mechanical and electric fault, prolong apparatus's life, reduce cost and increase product quality. At the same time, it helps to advancing design and manufacture level of welding machine power supply of my country.In this paper, the circuit configuration is ascertained on the basis of analyzing other circuit configuration of welding machine power supply, which links with the characteristics of endless-rolling. Then, the control model of power supply is designed. The components, controllers and protecting circuit which suit this circuit is collected through analyzing and calculating. And then, the working circumstances of this power supply circuit is simulated by the software PSPICE. On the basis of it, the bug of circuit is corrected. Finally, the parts of power supply circuit are tested and the results of both testing and simulating are compared.
