DAB converter

A Dual Active Bridge (DAB) converter is a high-frequency isolated DC-DC converter widely used in EV chargers, renewable energy systems.

tep-by-Step Setup1. Input Side

• Use DC Voltage Source
• Connect to a Full-Bridge Inverter (Universal Bridge) using IGBTs or MOSFETs
• Use a Phase Shift PWM Generator for control

2. Transformer

• Use an ideal transformer or a physical transformer model
• Ensure isolation and set turns ratio (e.g., 1:1, or for step-up/down)

3. Output Side

• Use another Full-Bridge Inverter (acting as rectifier)
• Connect to DC filter capacitor and load (or battery)

4. Control Strategy

• Implement a phase-shift controller:
• Shift output bridge gate signals relative to the input
