This paper presents a systematic way of designing and implementing a current controller for a Totempole Bridgeless Power Factor Correction (PFC) Converter. The State Space Averaging and Small Signal Modelling techniques are used to arrive at the Transfer Function. The controller is designed using the K-Factor approach and offers superior performance while tracking the reference current variations, load changes and input voltage fluctuations. Tuning the conventional PID controllers and finding the respective gains are more of a hit and trial method and therefore, the process must be repeated if the controller must be designed for some other requirements. The control strategy ensures that a sinusoidal and distortion-free current is drawn from the grid. The simulations are performed on MATLAB/SIMULINK to validate the robustness of the Controller and it conforms with the IEEE 519-2014 standards.
