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
