Three Phase Active Power Factor Correction in a Single Step

A single stage single switch power factor correction converter

The flyback-flyback single stage converter operated in DCM+DCM is easy to control bus voltage, but it hard to control stress of switch. We propose a new converter having low voltage stress on its switch. The flyback converter is simplified into buck-boost form. Then the PFC flyback transformer is replaced by an inductor The switch of both PFC and DC/DC stages are merged, and a diode is used to ...

A modular single-phase power-factor-correction scheme with a harmonic filtering function

Power supply systems in telecommunication applications employ several parallel-connected ac-to-dc and dc-to-dc power converters. Such a system offers modularity, redundancy, and is easily scalable to higher power levels. Such parallel-connected systems normally consist of several single-phase powerfactor-correction (PFC) stages connected to the same input utility. In this paper, a modular singl...

Single Phase Power Factor Correction: A Survey

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, in the recent years, 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...
