This paper describes improvements developed in an arc-welding power supply based on resonant inverters. A new standby operation sequence based on a sliding phase is proposed in order to reduce the discharge capacitor size. This standby solution also relieves the voltage specification of the resonant inductor. The interleaving operation of paralleled stages and the output connection wires are used to minimize the output capacitor current ripple and also extend the power supply's lifetime. Moreover, synchronous rectification is proposed in order to increase the efficiency and reduce the operation temperature of the output power stage. Finally, sequences are described for establishing and extinguishing arcs. Tungsten inert gas welding is selected for testing operations.
