Improved passive solutions to meet IEC 1000-3-2 regulation in low-cost power supplies

Over the past two decades, an increase in the use of electronic equipment and governmentally mandated energy conservation policies have changed the composition of electrical loads in normal commercial facilities. In this paper, the authors address the feasibility of the different passive LC filters in a single phase full-bridge rectifier to meet the IEC 1000-3-2 regulation in low-cost power supplies.
