A new topology for passive PFC circuit design to allow AC-to-DC converters to comply with the new version of IEC1000-3-2 regulations

The new edition of the IEC-1000-3-2 standard has led to the need for certain major concepts to once again come under the microscope for reconsideration. As the Class D template has disappeared, circuits designed to comply with the regulation by changing from Class D to Class A are now obsolete. The LC filter complies with the regulation in Class A with a very small inductance. To comply with Class D requirements a new circuit, which has been called a TLC rectifier, is proposed in this paper to reduce the passive device. The results obtained have been verified by computer simulation and experimental results.
