Dual Active Bridge Converter DC/DC Converter

Overview

10-kW single-phase isolated bidirectional DAB converter for EV charging, V2G, and high-frequency DC/DC studies.

This example shows a single-phase dual active bridge DC/DC converter, a key topology for bidirectional isolated power transfer. It is highly relevant for EV charging, V2G, and advanced DC power architectures.

The 10-kW converter uses two MOSFET full bridges, a coupling inductor, and a high-frequency transformer connecting an 800 V side and a 450 V side. Power transfer is controlled by phase shifting one bridge relative to the other.

This model gives the community a strong power-electronics seed post tied directly to modern charging infrastructure and energy-transfer applications. It is likely to attract both industrial and academic engagement.

Key Features

  • Bidirectional power flow
  • Isolated converter topology
  • 100 kHz switching frequency
  • Current regulation mode and direct phase-shift mode
  • Comparison of theoretical and actual power transfer

Getting Started

  1. Run the current-regulation mode to observe current-reference reversal.
  2. Switch to direct phase control and ramp the phase angle from negative to positive values.
  3. Compare simulated and theoretical power transfer, especially around dead-time effects.
