Sequential Phase-Shifted Model Predictive Control for a Multilevel Converter with Integrated Battery Energy Storage
(IEEE, 2020)
Cascaded converters have risen as a suitable solution for the connection of Utility-scale Battery Energy Storage Systems (BESS) to the grid. These converters allow to split the battery array into the power modules, reducing ...
Switching Control Strategy to Minimize Dual Active Bridge Converter Losses
(Institute of Electrical and Electronics Engineers, 2009-07-31)
A switching control strategy to control the power flow and minimize the total power losses of the dual active bridge converter topology is proposed in this paper. The control strategy consists of driving the bridge with ...
A 12 kW three-phase low THD rectifier with high-frequency isolation and regulated DC output
(Institute of Electrical and Electronics Engineers (IEEE), 2004-03-01)
A robust 12 kW rectifier with low THD in the line currents, based on an 18-pulse transformer arrangement with reduced kVA capacities followed by a high-frequency isolation stage is presented in this work. Three full-bridge ...
