DAB Single-Phase-Shift Control: Power Transfer, Phase Shift and Efficiency Design

Topic scope and research objective

A suitable research question is: how can the Dual Active Bridge & Isolated Converters approach represented by “Solar PV-Fed Dual Active Bridge Converter with MPPT and Single-Phase-Shift Control MATLAB Simulink Three-Phase Grid Integration” be evaluated using MATLAB Simulink, Simscape Electrical so that power-transfer tracking and DC voltage regulation are improved or maintained without creating unacceptable degradation in RMS transformer / tank current?

This article approaches Solar PV-Fed Dual Active Bridge Converter with MPPT and Single-Phase-Shift Control MATLAB Simulink Three-Phase Grid Integration from a optimization perspective so the page answers a different research need rather than repeating the main project description.

Technical focus

• PV array and MPPT dynamic response
• single-phase-shift DAB power transfer
• high-frequency transformer and leakage-inductance design
• three-phase inverter and grid-current validation

Optimization variables and objective functions

Optimization should target measurable performance rather than a single attractive plot. Candidate variables can be selected from the geometry, control, material or operating parameters represented by the model architecture below.

• Input source / PV or DC bus
• Primary bridge / switching stage
• High-frequency transformer and leakage / resonant network
• Secondary bridge / rectifying stage
• SPS or resonant control
• Voltage, current, power and loss measurement

Recommended sensitivity and parametric studies

• nominal rated-power operation
• input-voltage / conversion-ratio sweep
• light-load and full-load cases
• phase-shift / switching-frequency sweep
• device / parasitic or soft-switching robustness case

Change one factor at a time for physical interpretation, then use multi-variable optimization only after the dominant sensitivities are understood.

Optimization metrics and result selection

Report the baseline, best candidate and at least one robustness case so improvement is not based on one narrow operating point.

PhD and journal research extensions

• wide-range soft-switching optimization across voltage and load
• multi-objective magnetics / resonant-tank design for efficiency and power density
• advanced phase-shift or predictive control for transient performance
• SiC / GaN loss and thermal co-optimization with bidirectional operation

For PhD researchers and postgraduate scholars working internationally, this topic can be adapted to a university proposal, published reference paper or independently defined research gap. The model scope can be aligned with the required software version, parameter set, dataset, disturbance profile, geometry, controller structure and reporting format while preserving reproducibility and clear technical attribution.
