A full-bridge conversion arrangement controlled through the documented relative switching-leg phase shift.

## What it represents

A full-bridge conversion arrangement controlled through the documented relative switching-leg phase shift.
On a schematic, identify the bridge legs, magnetic path and phase-shift control references and trace the secondary rectification and output regulation. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
Phase-shift control is a specific operating arrangement; it is not established merely by showing four power switches.
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 bridge legs, magnetic path and phase-shift control references.
- Trace the secondary rectification and output regulation.

## Information to show or reference

- Label the bridge legs, magnetic path and phase-shift control references.
- Cross-reference the secondary rectification and output regulation.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.

## Important distinction

Phase-shift control is a specific operating arrangement; it is not established merely by showing four power switches.

## Facts

- Common schematic mnemonic: PSFB — descriptive only; project/device documentation defines reference designations.
- Terminal / interface focus: The bridge legs, magnetic path and phase-shift control references
- 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.
