Mitigation of Cross-coupling effects in PV-D-MPPT systems with T-C-T configuration of String-Integrated-Converters using INC Algorithm

This paper proposes the Total-Cross- Tied (T-C-T) configuration of String-Integrated-Converters (SICs) to photovoltaic-distributed -maximum power point tracking (PV-D-MPPT) architecture. The proposed configuration mitigates the cross-coupling effects existed in the series configuration. The non-isolated boost converter is considered as the SIC. The incremental conductance (INC) MPPT algorithm is used to extract the maximum power. The implementation of the proposed configuration is evaluated and correlated with the conventional configuration under different partial shading conditions (PSCs).
