SWITCHMODE POWER-FACTOR-CORRECTED DIRECT CONVERSION TYPE FORWARD CONVERTER

Advantages of Using a Two-Switch Forward in Single-Stage Power Factor Corrected Power Supplies

Simulation of Active Power Factor Correction Using Boost Type Converter

With the vast development in the usage of Power electronic devices like Rectifiers (nonlinear loads) the current drawn from the line is distorted resulting in a High Total Harmonic Distortion (THD) and Low Power Factor (PF). Hence there is a continuous need for Power factor improvement and reduction of line current harmonics. The most popular topology for Active PFC is a boost converter as it d...

Fuzzy Supervisory Controller for Improved Voltage Dynamics in Power Factor Corrected Converter

This paper investigates performance of Fuzzy Supervisory Controller (FSC) in control of power converters. A FSC module is added to conventional narrow bandwidth voltage regulator in Power Factor Corrected (PFC), Voltage Source Converter (VSC) to improve DC bus voltage regulation. PFC converter is selected for this work as conventional design of the PFC converter requires narrow bandwidth DC bus...

Power Factor Corrected Bridgeless Buck–Boost Converter-Fed with Adjustable-Speed BLDC Motor Drive

This paper presents a power factor corrected (PFC) bridgeless (BL) buck–boost converter-fed brushless direct current (BLDC) motor drive as a cost-effective solution for low-power applications. An approach of speed control of the BLDC motor by controlling the dc link voltage of the voltage source inverter (VSI) is used with a single voltage sensor. This facilitates the operation of VSI at fundam...
