Theoretical study and experimental verification of low cost, integrated and efficient AC/DC power supplies using time-multiplexing control

Description The project will improve the efficiency and reduce the size and cost of currently commercially available single-phase AC/DC power supplies, consisting of separate power factor correction and DC/DC power processing stages. We will combine these two stages into a single power stage, by slightly modifying existing AC/DC converter circuits, and employing a time-multiplexing control technique. The new circuits will have fewer components and simpler circuitry while maintaining same functions of a normal AC/DC power supply. The technique can be applied to any AC/DC converter design and is able to be implemented in the power supply industry in the short term.
