Push-pull converter

A Push-Pull Converter is a type of DC-DC converter that efficiently steps up or steps down a DC voltage using a center-tapped transformer

How It Works

The Push-Pull converter uses:

• A center-tapped transformer
• Two switches (MOSFETs, BJTs, or IGBTs)
• A rectifier and filter capacitor on the output side

🔁 Operation:

• Switches operate alternately (never ON at the same time)
• Each switch applies input voltage to half of the transformer winding
• Transformer generates alternating current (AC) in the secondary
• Output is rectified and filtered to produce DC
