Abstract - Hybrid Electric Vehicles (HEV) usually need power conditioning, typically rectification which uses non linear devices, that produces a non-sinusoidal line current due to their non- linear input characteristics. The reduction of line current harmonics for enhancing the efficiency is Power Factor Correction. For active power factor topologies, there exist bridged and bridgeless power converter circuits. This paper focuses on a bridgeless
Interleaved Boost Converter (IBC) for shaping the line current waveform. Moreover, this paper discusses about various boost converter topologies which are designed and simulated using MATLAB - SIMULINK for active power factor correction. Performance parameters such as the
Total Harmonic Distortion (THD) in the line current, input power factor and displacement factor are investigated for all the topologies. On comparison, this paper insists on the fact that Bridgeless Interleaved Boost Converter has higher input power factor and lower harmonics in the line current which is verified through simulation.
Passive devices like capacitor banks are used in
Passive power factor correction. By using passive power factor correction the vehicle becomes bulkier and also becomes uneconomical. Therefore active power factor correction is implemented using power electronic devices to improve the efficiency of the PFC stage by lowering the conduction and switching losses. The active power factor correction is further classified into high frequency active PFC and low frequency active
PFC.
