Ket : The increasing pervasiveness and acceptance of household and personal electronic devices in recent years has created new challenges for switched-mode power supply (SMPS) designers in terms of cost, size and performance. For SMPS that operate off of the ac mains one particular set of performance specifications is the magnitude of the individual harmonic input currents above the fundamental. The undesirable effects of high harmonic input current content include increased RMS line currents limiting the power available to an ac load for a given ac service wire gauge, increased neutral currents in 3-phase systems, possible ac system instability and line voltage distortion. To mitigate these negative effects international standards such as EN 61000-3-2 [1] have been developed to limit the harmonic input current magnitudes of many ubiquitous electronic devices
