AC-DC DAB Converter with Power Factor Correction

Modified Bi-directional AC/DC Power Converter with Power Factor Correction

Most existing power  converters and industrial motor drive systems draw non-sinusoidal currents from the supply. Non-sinusoidal currents contained harm harmonics disturb the power supply which it causes serious concern for reliability. Other equipments that use the same power supply are adversely affected. This paper suggests the operation and performance of a new modified AC/DC converter that ...

Low Cost AC/DC converter with Power Factor Correction

AC/DC Converter with Active Power Factor Correction Applied to DC Motor Drive

–Harmonic pollution and low power factor in power systems caused by power converters have been of great concern. To overcome these problems several converter topologies using advanced semiconductor devices and control schemes have been proposed. This investigation is to identify a low cost, small size, efficient and reliable ac to dc converter to meet the input performance index of UPS. The per...

Implementation of Single Stage Three Level Power Factor Correction AC-DC Converter with Phase Shift Modulation

A new three-level ac–dc single-stage converter that can operate with standard phase-shift pulse width modulation is proposed in this letter. In this letter, the operation of the converter is explained, and its feasibility is confirmed with experimental results obtained from a prototype converter. Finally, the efficiency of the new converter is compared with that of a previously proposed convert...

A Three Level Integrated Ac-dc Converter with Power Factor Correction

In this paper, a three-level integrated ac–dc converter with power factor correction is presented. The proposed converter integrates the operation of the boost power factor correction and the three-level dc–dc converter. The converter is made to operate with two independent controllers—an input controller that performs power factor correction and regulates the dc bus and an output controller th...
