Abstract

In this paper, a new single-phase single-ended primary-inductor converter (SEPIC) topology-based ac-dc converter is proposed pursuing only a singular switch for power conversion. The proposed converter exhibits higher input power factor, moderated total harmonic distortion (THD) in the input line current complying with IEEE-519 standards and high voltage gain compared to its traditional counterpart. In addition, the proposed topology displays promising performance under unexpected load introduction and load variations. Furthermore, the proposed converter causes a very low power loss comparing to its conventional topologies for the utilization of only a single switch to signal control. All the simulations have been performed in MATLAB/Simulink environment which upholds the performance of the topology and validates the philosophy of proposed converter.
