Abstract	The paper describes some important design considerations in developing a variable three-phase AC-DC converter with unity power factor and the minimum harmonic content of the line current using boost converter topology. The design details of expanding a single-phase converter into a three-phase system are presented. This article also describes the major problems encountered in carrying out such essential modifications, together with their practical solution. A detailed circuit design is included. The prototype circuit was tested for both resistive and inductive loads. The results of operating the converter with a typical DC motor load are also presented
