Abstract
A power supply unit includes a plurality of power trains and a control assembly. Each power train includes a power factor correction circuit that receives an AC input and generates a first DC output, and a DC/DC converter circuit that receives the first DC output and generates a second regulated DC output. The control assembly is coupled to the power trains and is operative to monitor outputs supplied by the power trains. In response to the power train outputs, the control assembly provides control signals to each power train.
