Modeling and Analysis of Single-phase Boost Converter with Power Factor Correction Control

When ac/dc converters are widely used in modern power system, harmonic component generated from non-linear electronic devices becomes a major issue. The power factor correction (PFC) can be employed to reduce harmonic components and improve transmission efficiency. This paper presents three approaches to model a PFC circuit implemented in a single-phase ac/dc boost converter, which is mathematical modeling, detailed modeling and average modeling. Harmonic analysis of this circuit is also carried out. These models are performed in MATLAB/Simulink and SimPowerSystems. Simulation results are presented and compared.
