Analysis and Implementation of a Single-Phase Bridgeless Hybrid Switched-Capacitor Rectifier in DCM for Power Factor Correction

Blog Article

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) Dishwasher Basket Wheel 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 Missouri Star Publications 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.
