A Novel Segmented Component Injection Scheme to Minimize the Oscillation of DC-Link Voltage Under Balanced and Unbalanced Conditions for Vienna Rectifier

IEEE transactions on power electronics, 2019
This paper investigates a Vienna rectifier as a charger for series-connected battery packs. Focusing on carrier-based pulsewidth modulation (CBPWM), the ripple current flowing through the neutral point (NP) results in the voltage oscillation if the loads

High gain bidirectional DC-DC converter with reduced component count

2017 National Power Electronics Conference (NPEC), 2017
Solar Photovoltaic system as a source and battery as an intermediary load necessitates the development of bidirectional dc-dc converter. Conventional battery loads are rated at 12 V to 48 V. High gain is required both in step up and step down modes to supply the ac grid or charge from the grid.

Embedding image watermarks in dc components

IEEE Transactions on Circuits and Systems for Video Technology, 2000
Both watermark structure and embedding strategy affect robustness of image watermarks. Where should watermarks be embedded in the discrete cosine transform (DCT) domain in order for the invisible image watermarks to be robust? Though many papers in the literature agree that watermarks should be embedded in perceptually significant components, dc ...

Integrated Magnetic Component based Analysis for Interleaved DC-DC Buck Converter

2005 International Conference on Power Electronics and Drives Systems, 2006
Integrated magnetic components are used to reduce the size of the converter and improve efficiency. However, no analysis leading to simple equivalent circuit of the coupled system with arbitrary number of phases has been presented so far. This paper proposes a circuit based analysis method for such converters, which leads to precise performance ...

A consideration of loss component in model control dc-dc converter

2015 International Conference on Renewable Energy Research and Applications (ICRERA), 2015
Recently, the energy saving is required. It is necessary for the energy saving to operate the electric device in the sleep mode. Therefore, the output voltage rises abnormally because the dc-dc converter is required the operation in the discontinuous current mode.

Series resonant high‐voltage DC–DC converter with reduced component count

IEEJ Transactions on Electrical and Electronic Engineering, 2016
This paper proposes a novel zero‐current‐switching series resonant high‐voltage DC–DC converter with reduced component count. The series resonant inverter in the proposed topology has two power switches (insulated‐gate bipolar transistors, IGBTs), two resonant capacitors, and only one high‐voltage transformer (HVT) with center‐tapped primary windings ...
