A DC conversion stage using two switching legs to apply the documented waveform to a magnetic primary.

## What it represents

A DC conversion stage using two switching legs to apply the documented waveform to a magnetic primary.
On a schematic, identify the four switches, two bridge midpoints and transformer winding and trace the secondary transfer circuit and bridge control interfaces. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
A full-bridge DC converter includes a secondary DC power path; a full-bridge inverter instead supplies an AC output arrangement.
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 four switches, two bridge midpoints and transformer winding.
- Trace the secondary transfer circuit and bridge control interfaces.

## Information to show or reference

- Label the four switches, two bridge midpoints and transformer winding.
- Cross-reference the secondary transfer circuit and bridge control interfaces.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.

## Important distinction

A full-bridge DC converter includes a secondary DC power path; a full-bridge inverter instead supplies an AC output arrangement.

## Facts

- Common schematic mnemonic: FB-DC — descriptive only; project/device documentation defines reference designations.
- Terminal / interface focus: The four switches, two bridge midpoints and transformer winding
- Artwork scope: Original conceptual topology block; not a complete switch-level circuit.

## Public references

- [Power topology selection and public topology tutorials](https://www.ti.com/video/series/power-topology-selection.html) — Texas Instruments. Public primary manufacturer documentation establishes the component function or circuit/topology relationship. Preview geometry and drafting explanations are independently authored.
