Nput Power Factor News Today

A new single-phase ac-dc cúk converter topology is presented in this paper, which utilizes single control switch for the power transformation. The proposed topology offers 0.998 input power factor which is almost unity, 2.41% input current total harmonic distortion maintaining IEEE-519 standards without any additional filter at the input side, which is considered to be the best performance of the presented converter. The proposed topology also produces highest voltage gain of 7.16. Moreover, th...

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 introduct...
