School of Electrical and Electronic Engineering 2016 IEEE Region 10 Conference (TENCON) Photovoltaic systems Multilevel converter 4 p. The full-row connection of dc-links provides an alternative configuration for the cascaded H-bridge (CHB) converter in large-scale grid-connected photovoltaic systems. In each stage, a single PV string is connected to all phases through isolated dc/dc converters. The per-phase power imbalance issue and second-harmonic voltage of the dc-link capacitors are alleviated by using this topology. This paper studies the low-voltage ride-through (LVRT) capability of the HB inverter with full-row connection in a grid-connected photovoltaic power plant (GCPVPP). A control algorithm is implemented for the isolated dc/dc converters which balances the capacitor voltages during voltage sags and reduces the second-harmonic voltage ripple of the dc-link capacitors. The performance of the grid-connected HB inverter with LVRT capability is investigated on a 3-MVA single-row, three-level CHB converter for the GCPVPP connected to a 6.6 kV grid.
