Research on Hybrid Voltage-Power Switching Control Strategy of Grid-Connected Two-Stage Photovoltaic System for Low Voltage Ride Through Faults

IEEE Access
For two-stage grid-connected photovoltaic (PV) system, if the low voltage ride through (LVRT) faults occur in the grid side, because the grid voltage falls to a relative low value and the output current is limited, then the output power of inverter ...

Voltage and Current Programmed Modes in Control of the Z-Source Converter

2008 IEEE Industry Applications Society Annual Meeting, 2008
The Z-source converter (ZSC) is an alternative power conversion topology that can both buck and boost the input voltage using passive components with improved reliability. Dynamic modeling of the ZSC from different perspectives has been studied. So far, based on these models, the dc-link voltage is controlled using direct measurement, or through ...
