Abstract
A welding-type power supply includes a controller, a preregulator, a preregulator bus, and an output converter. The controller has a preregulator control output and an output converter control output. The controller has a converter control output connected to the control input, and a flux balancing module. The converter control output is responsive to the flux balancing module such that the flux in the transformer remains balanced.
