 Abstract:

A substantial increase in the energy saving measurements has led to a remarkable growth of grid tied PV systems. A grid tied PV systems consisting of modular current fed dual active bridge DC-DC converter with cascaded multilevel inverter. Due to frequency voltage variations in the DC link it affects the performance of MPPT block and thus reduces the overall efficiency. The proposed power mitigation control based CFDAB model is implemented to prevent low frequency voltage variation propagating from DC link to PV side. This module is simulated using MATLAB/Simulink. The experimental results are given to approve the performance of the system.

Keywords:  

Current Fed Dual Active Bridge, Small Dc link capacitor, low frequency ripple, MPPT, high-frequency link
