An investigation on Power Quality Enhancement of Unity Power factor rectifier is sought in this paper. The rapid growth of non linear devices has resulted in degradation of power quality. On long run these distortions in low, medium and high power devices will be a matter of concern on our pace to a smart grid. The devices when connected to the distribution side can bring about distortions to input supply due to their non linearity. Active and passive power factor strategies exist in the current system. The Buck-Boost-Type rectifier in discontinuous mode and the effect of feedback on the Power Quality is dealt in this paper using simulation results. A hardware prototype with power factor correction has been implemented.
