Performance Analysis of PV Standalone System with High-Power DC–DC Converter Application to Induction Machine Drive

This paper presents a steady-state analysis of the bidirectional dual active bridge (DAB) dc–dc converter. This paper also presents the analysis of zero-voltage switching (ZVS) boundaries for buck and boost modes while considering the effect of snubber capacitors on the DAB converter is also presented. This is the new model for producing the equations for average and rms device currents. The proposed model can be used to predict the converter efficiency at any desired operating point. The proposed model was built for an aerospace energy storage application. The results obtained from the model under various voltages, currents and power transients verify converter operation and validate the proposed controller performance during bidirectional power transfer. Finally in this project the proposed converter is applied for standalone PVcell applications. The simulations results are carried by using MATLAB/SIMULINK SOFTWARE
