A HVDC shunt tap based on unidirectional hybrid modular DC-DC converter with simultaneous charging and sequential discharging of capacitors
(
Elsevier Ltd
, 2018 , Article)
In this paper, a new HVDC shunt tap is proposed. The proposed configuration consists of a unidirectional hybrid modular DC-DC converter followed by a voltage source converter for DC-AC conversion to feed a local AC network ...
A Grid-Connected Capacitor-Tapped Multimodule Converter for HVDC Applications: Operational Concept and Control
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
In this paper, a dc-ac buck converter is proposed as a grid-side converter in high voltage dc (HVdc) transmission systems for high-power renewable energy source grid integration. The proposed architecture consists of ...
Self-balanced non-isolated hybrid modular DC-DC converter for medium-voltage DC grids
(
Institution of Engineering and Technology
, 2018 , Article)
Here, a new bi-directional hybrid modular non-isolated DC-DC converter is proposed where it consists of a boost converter (BC) fed from the high-voltage (HV) side. At the BC output stage, a certain number of half bridge ...
