Single stage full bridge converter with power factor correction

Abstract

The full-bridge converter with isolation transformer is the preferred topology for medium and high power SMPS. A simple topology modification, i.e. the addition of two input inductors, and appropriate control methods permit to control simultaneously and accurately the output voltage and the input current, performing a new single stage SMPS.

PFC Bridge Converter for Voltage-controlled Adjustable-speed PMBLDCM Drive

“…Therefore, suitable measures for mitigation of PQ problems are necessary. Therefore, the use of power factor correction (PFC) topologies [9][10][11][12][13][14][15][16][17][18][19] is recommended for such drives. A standard IEC 61000-3-2 [20] is a power quality standard that outlines allowable limits of different harmonics for the drives in the low power range (current less than 16 A).…”

“…A PMBLDCM rated at 3.75 kW, 250 V, 1500 rpm, and 23.87 Nm torque is used to drive an air conditioner compressor. There are many DC-DC converter topologies available, including buck, boost, and buck-boost with variations of isolated and non-isolated topologies and a number of switches (single, two, or four switches) [10][11][12][13][14][15][16][17][18][19]. A buck bridge DC-DC converter is used in this work due to the low voltage, isolation, and high power requirements of the load in a wide output voltage range.…”

“…A detailed modeling, design, and performance evaluation of the proposed speed control scheme with the PFC converter for an air conditioner compressor is presented to demonstrate high efficiency and reduced energy consumption with desired speed control. The features of the speed control using the DC link voltage control, power factor correction at input AC mains, and reduced THD of AC mains current are added advantages of the buck bridge PFC converter [12][13][14][15][16][17].…”
