Bridgeless power factor correction (PFC) converter is popular for reducing the conduction losses of semiconductors. In this paper, a novel bridgeless Cuk PFC converter is proposed. Compared to the conventional Cuk PFC converter, the number of conducting semiconductors in the proposed bridgeless Cuk PFC converter is reduced, contributing to lower co...

Bridgeless power factor correction (PFC) converters have a reduced number of semiconductors in the current flowing path, contributing to low conduction losses. In this paper, a new bridgeless high step-up voltage gain PFC converter is proposed, analyzed and validated for high voltage applications. Compared to its conventional counterpart, the input...

In this study, a novel AC-DC bridgeless buck converter for power-factor-correction (PFC) applications with the inherent current-shaping ability and high PFC performance is proposed. Under a certain operation condition, dead zones in the proposed converter are reduced inherently compared with its conventional buck PFC counterpart, which result in hi...

The bridgeless buck power factor correction (PFC) converters feature the merits of low output voltage and high efficiency while their nature existing dead angles in the input current deteriorate the input current harmonics and power factor (PF). Aiming to reduce the dead angles, a new bridgeless buck PFC converter is proposed in this paper. Through...

A novel single-phase AC–DC bridgeless boost power factor correction (PFC) converter is proposed in this paper. This converter is constructed by paralleling a boost and a buck–boost topology. It features a solid connection between the input and output ground terminals leading to low common mode noise. Moreover, it possesses a high PFC performance wh...
