Analysis of High Power Factor AC-DC Boost Converter.

Integrated Buck-Buck-Boost AC/DC Converter

Single-Stage transformerless AC/DC converter received much attention in the universal line application. Unlike the existing converters a new high step-down transformerless single-stage single-switch AC/DC converter is proposed. The topology integrates a buck-buck-boost converter with low intermediate bus and output voltage. The converter utilizes a buck converter as a PFC cell and buck-boost co...

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 ...

Boost Converter for Power Factor Correction of DC Motor Drive

With the increasing demand for power from the ac line and more stringent limits for power quality, power factor correction has gained great attention in recent years. A variety of circuit topologies and control methods have been developed for the PFC application. While the discontinuous conduction mode (DCM) converters such as boost and flyback converters are well suited for low power applicati...

Low Cost AC/DC converter with Power Factor Correction

Flywheel Energy Storage System Based on Boost DC-AC Converter

To extend the operating speed range of a conventional configuration of FESS (flywheel energy storage system), an additional DC-DC boost converter is required between the machine and grid side converters to regulate the output voltage. This paper presents a new FESS based on three-phase boost inverter topology. The proposed system facilitates voltage boost capability directly in a single-stage. ...
