| description |
This work presents the quantitative and qualitative analysis, as well as the experimental results of a practical implementation of the Single-Phase Bridgeless Hybrid Switched Capacitor Rectifier operating in discontinuous conduction mode (DCM) to achieve a high input power factor. Operating in DCM provides several advantages, including natural power factor correction (PFC) behavior of the input current and reduced semiconductor switching losses. The paper begins with a literature review on key studies of hybrid switched-capacitor converters with a high power factor. Subsequently, the converter analysis, including its modulation scheme, operational stages and design methodology, is detailed. The proposed approach is validated with results from a practical prototype implementation, achieving an output voltage of 1200 V and an output power of 315 W from an input voltage of 220 V. The converter demonstrated an efficiency of 97.3 %, a power factor of 0.99, and harmonic distortion levels within the limits specified by IEC61000-3-2.
