| Abstract: | To overcome the shortcomings of conventional arc welding inverters, a new soft switching topology, together with the phase shifted soft switching and peak current control technology, is used to develop a new soft switching arc welding inverter. The test results show that the full range soft switching and the functions of auto correction and current limiting are realized for the inverter, solving the problem of magnetic bias of the power transformer. |
