Solar Fed Dual Active Bridge Converter with MPPT

Simulink model of solar PV fed DAB converter with MPPT, phase shift control, efficiency and power transfer analysis.

This project presents a MATLAB/Simulink model of a Solar Photovoltaic (PV) fed Dual Active Bridge (DAB) DC-DC converter for isolated and efficient power conversion.

The system integrates a PV source with Maximum Power Point Tracking (MPPT) control and a high-frequency isolated DAB converter using phase shift modulation. The model is suitable for renewable energy systems, electric vehicle (EV) applications, and DC microgrids.

Key Features:

- Solar PV modeling with variable irradiance

- MPPT control (Perturb & Observe algorithm)

- Dual Active Bridge (DAB) converter topology

- High-frequency transformer isolation

- Phase shift control (Single Phase Shift - SPS)

- Bidirectional power flow capability

- Efficiency estimation and power transfer analysis

- Suitable for 1 kW to 5 kW applications
