Power source for high current welding |
摘要 |
An inverter based power source for electric arc welding where the power source includes a high switching speed inverter for driving the primary side of an output transformer that has a primary circuit with current greater than 250 amperes and a secondary circuit with a current having an operating range with a maximum current greater than 700 amperes and an output rectifier to rectify the secondary current into a DC current suitable for welding. <IMAGE> |
