Model-Free Predictive Control Based on RLS Algorithm for Grid-Forming Inverters With Virtual Synchronous Generator Open
As a key element to connect renewable energy sources, grid-forming inverters (GFIs) mostly use droop control as an outer loop, but it can cause a swift change in the system frequency when disturbances arise. In the role of the inner loop c…

Hybrid Resonant DC–DC Converters for DC Transformers in DC Distribution Networks With Limited Reverse Power Flow Range Open
In DC distribution networks integrating distributed generation, DC transformers (DCT) exhibit asymmetric forward and reverse power flows, with reverse power flow range being limited. Based on this characteristic, this paper proposes a hybr…

Modulation for Cascaded Multilevel Converters in PV Applications With High Input Power Imbalance Open
Cascaded multilevel inverters, such as the cascaded H-Bridge (CHB) converter, are an attractive solution for multi-string photovoltaic (PV) systems, because they enable direct connection to the medium voltage grid and maximum power point t…
