Design of a Single Phase Converter with High Power Factor

A novel Boost high power factor converter with UCC28019 was designed.The work principle of the system was introduced.Its sections were analyzed and designed respectively in detail.During the design of inductor,a new Boost inductor winding with thin copper tape craft was adopted.It could effectively reduce collection skin effect,improved the switch modulating profile of the Boost converter,and reduced the temperature rising of magnetic element.Experimental results of the designed 350 W prototype proved that the Boost high power factor converter was rational and reliable,its power factor could reach 0.993,its application prospect was wide.
