A hybrid bridgeless AC‐DC converter topology

International Journal of Circuit Theory and Applications, 2023
SummaryBridgeless ac‐dc converters are the optimal choice for many applications, as they offer many advantages such as low distorted supply current, high power factor, and improved efficiency. This paper presents a new topology for a single‐phase bridgeless ac‐dc converter.

A three-level integrated AC-DC converter

2012 IEEE Energy Conversion Congress and Exposition (ECCE), 2012
In this paper, a new integrated three-level ac-dc converter 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 ...

An AC/DC converter with high power factor

IEEE Transactions on Industrial Electronics, 2003
The television receiver often employs a capacitor-input-type rectifier. In this case, it is regulated as a class D piece of equipment. This paper presents a novel ringing-choke-converter-type switching regulator, which functions as an active filter. The proposed circuit features a simple circuit configuration and cost effectiveness.

Fast Synchronous Ac-Dc-Transfer with Thermal Converters

2004 Conference on Precision Electromagnetic Measurements, 2004
The most accurate measurements of the rms (root mean square) values of ac (alternating current) voltages are performed by means of thermal converters (TC) (Klonz, 2002) and digital sampling procedures (Ihlenfeld, 2001 and Ihlenfeld, et. al., 2003) (at low frequencies) with uncertainties of the order of some fractions of muV/V.

AC/DC/AC converter based on parallel AC/DC and cascaded multilevel DC/AC converter

2012 Students Conference on Engineering and Systems, 2012
This paper presents a single phase AC/DC/AC converter based on parallel AC/DC and cascaded multi-level DC/AC Converter. For a two-cell AC/DC/AC converter, two units of full-bridges are connected in parallel and two units of half-bridges are connected in cascade.
