Abstract—This paper presents the comparison of various current control techniques employed for a bridgeless interleaved boost converter for improving the power quality. The major control strategies discussed in this paper are: peak current, average current mode and borderline current control. These strategies are implemented in MATLAB/SIMULINK and the performance of the proposed converter is compared under open loop and closed loop operation. From the results, the input current waveform was close to sinusoidal implying high power factor and reduced harmonics for borderline control.

INTRODUCTION
For automotive and battery charging applications, a regulated DC supply is required and since AC supplies are more commonly available, a suitable AC-DC converter becomes mandatory for such applications. These AC-DC converters involve a number of non-linear devices which reduce the system power factor and introduce harmonics in the power system leading to adverse effects. Hence it is essential to use a suitable power factor correction technique to condition the supply current. This paper presents the design and implementation of one such Active Power
Factor corrected AC-DC Converter topology, which results in an improved supply power factor and reduced line current harmonics. A novel converter topology, namely the
Bridgeless Interleaved Boost Topology for active power factor correction, along with a closed loop current control technique to condition the supply current has been
