A COMPARATIVE STUDY OF ACTIVE POWER FACTOR CORRECTION AC-DC CONVERTERS FOR ELECTRIC VEHICLE APPLICATIONS

The rising growth in the usage of electronic equipment's internally works on DC voltage. The conversion from AC to DC will cause high current peaks which lead to harmonic distortion of the supply current and low power factor. This results in voltage distortion, low efficiency, and poor power factor. Active Power Factor Correction (APFC) is implemented in circuits to shape the input phase currents, so that they are sinusoidal in nature and are in phase with the input phase voltages. A suitable DC-DC converter is proposed and Interleaved Boost Converter (IBC) topology is discussed in this paper. The performance of two-phase uncoupled and directly coupled Interleaved Boost Converter (IBC) have been analyzed and compared with classical boost converter. Advantages of Interleaved Boost Converter compared to the classical Boost Converter are low total harmonic distortion, low input current ripple, high efficiency, faster transient response, and improved reliability. The waveforms were obtained using MATLAB/SIMULINK. Using the simulation results, the best topology is concluded.
