Abstract
Systems and methods for providing welding power supplies with interleaved inverter circuitry are described. In one embodiment, a welding power supply includes, for example, a first inverter circuit and a second inverter circuit that are arranged in parallel. A voltage source or a current source is coupled to a first same node of the first inverter circuit and the second inverter circuit. A filter inductor is coupled to a second same node of the first inverter circuit and the second inverter circuit. The output current of the filter inductor is halved in frequency by disabling one of the first inverter circuit and the second inverter circuit.
