Solid-state switch-mode rectification converters have reached a matured level for improving
power quality in terms of power-factor correction (PFC), reduced total harmonic distortion at …

Solid-state switch mode AC-DC converters having high-frequency transformer isolation are
developed in buck, boost, and buck-boost configurations with improved power quality in …

This study presents various configurations, control schemes and design of single-phase
power factor controller (PFC) topologies for permanent magnet brushless DC motor …

Low cost passive power factor correction (PFC) and single-stage PFC converters cannot
draw a sinusoidal input current and are only suitable solutions to supply low power levels …

Power-factor correction has been one of the hottest topics during the last few years and,
hence, many new circuits have appeared. In general, it is assumed that preregulators based …

This work presents a review of power-factor-correction (PFC) circuits for low-and medium-
power single-phase power supplies. The main idea is not just to show the state of the art of …

When a power factor corrector (PFC) is designed with a relatively fast output-voltage
feedback loop, the static and dynamic behaviors of the power stage are different from those …

The classical design of an active power factor corrector (PFC) leads to slow transient
response in this type of converter. This is due to the fact that the compensator placed in the …

In recent years, several AC/DC converters have been presented in order to meet the power
quality regulations, while maintaining the lowest number of components with the purpose of …

Four new topologies of active input current shapers (AICSs) for converters with
symmetrically driven transformers (such as half-bridge, full-bridge and push-pull) have been …
