| Abstract: | Aiming at the existence of DC arc welding generator of large power consumption,cost materials,large noise and bad control precision,this paper presents a new topology circuit to replace the traditional control circuit,the topology circuit is not controlled by the rectified voltage by DC/DC converter are welding DC voltage and DC current.This paper focuses on the analysis of semi-type isolation DC/DC converter main circuit and a control portion of the PWM wave generation and system protection measures.This paper detailed introduces the calculation method of engineering parameters,and verified by experiments in this paper the circuit topology and the control method and the parameter calculation method is effective. |
