Converters using active switches can improve the harmonic components of input current and the power factor. Moreover, the use of these converters can result in a reduction in the size of the footprint. However, the increase in switching losses and EMI due to high-frequency switching is a disadvantage of these converters. In this study, we propose a new active rectifier circuit topology that can reduce the switching losses and EMI by soft-switching operation. Almost unity fundamental power factor and practically good characteristics of input current harmonics can be achieved by employing a simple switching control method. The characteristics of the power and input current harmonics of the proposed converter are analyzed. Small-scale experiments were conducted and the operation principles and characteristics of the rectifier were determined.
