Forward Converter Transformers

Forward Converter Transformers

The forward converter does appear similar to the flyback transformer, but it is actually very different. A forward converter transformer transfers its energy instantly (transformer action), unlike the flyback which stores and then releases that stored energy to the SEC side.

A forward converter transformer may appear to have two PRI windings, but in fact, one of these is what we call a reset winding. It is used to demagnetize the core when the transformer is “off”.  This type of transformer has lower magnetizing currents due to its high primary inductance….although this type of transformer is often more costly.

This is a straightforward type of transformer used at high switching frequencies with good efficiency values.
