Single phase power factor correction: a survey

TLDR

Recent standards and recommendations have heightened interest in power‑factor correction circuits, which include many sinusoidal and nonsinusoidal line‑current solutions. This paper reviews the most interesting single‑phase, low‑power power‑factor correction solutions. The solutions are classified by line‑current waveform, energy processing, switch count, control loops, and other criteria. The review highlights the major advantages and disadvantages of each solution and identifies their application fields.

Abstract

New recommendations and future standards have increased the interest in power factor correction circuits. There are multiple solutions in which line current is sinusoidal. In addition, a great number of circuits have been proposed with nonsinusoidal line current. In this paper, a review of the most interesting solutions for single phase and low power applications is carried out. They are classified attending to the line current waveform, energy processing, number of switches, control loops, etc. The major advantages and disadvantages are highlighted and the field of application is found.
