A converter arrangement driving two primary paths alternately through the documented coupled winding.

## What it represents

A converter arrangement driving two primary paths alternately through the documented coupled winding.
On a schematic, identify the centre-tapped primary connection, two switches and winding polarities and trace the secondary rectification and output path. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
Push-pull uses its specific primary arrangement; it differs from a half-bridge applied to a single untapped primary.
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 centre-tapped primary connection, two switches and winding polarities.
- Trace the secondary rectification and output path.

## Information to show or reference

- Label the centre-tapped primary connection, two switches and winding polarities.
- Cross-reference the secondary rectification and output path.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.

## Important distinction

Push-pull uses its specific primary arrangement; it differs from a half-bridge applied to a single untapped primary.

## Facts

- Common schematic mnemonic: PUSH-PULL — descriptive only; project/device documentation defines reference designations.
- Terminal / interface focus: The centre-tapped primary connection, two switches and winding polarities
- Artwork scope: Original conceptual topology block; not a complete switch-level circuit.
