A conversion stage with controlled bridges on both sides of a coupled magnetic link.

## What it represents

A conversion stage with controlled bridges on both sides of a coupled magnetic link.
On a schematic, identify the two DC ports, both active bridges and isolation boundary and trace the bidirectional energy path and bridge control references. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
Two actively switched sides distinguish a DAB from a primary bridge with passive secondary rectification.
The preview is a conceptual topology reference rather than a complete power-stage circuit. Switching sequences, magnetic design, component selection and control/protection details belong in the equipment design documentation.

## How to read it

- Identify the two DC ports, both active bridges and isolation boundary.
- Trace the bidirectional energy path and bridge control references.

## Information to show or reference

- Label the two DC ports, both active bridges and isolation boundary.
- Cross-reference the bidirectional energy path and bridge control references.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.

## Important distinction

Two actively switched sides distinguish a DAB from a primary bridge with passive secondary rectification.

## Facts

- Common schematic mnemonic: DAB — descriptive only; project/device documentation defines reference designations.
- Terminal / interface focus: The two DC ports, both active bridges and isolation boundary
- Artwork scope: Original conceptual topology block; not a complete switch-level circuit.
