This circuit can suffer from the same ringing and possible transformer saturation problems described in the basic approach. Figure 3: Transformer-Isolated Gate Drive with DC Restore (Click on image to ...

This gate-drive transformer (GDT)circuit allows the drive signal to the MOSFET to range from 50% down to 0%, while still offering a fast turn-off that cannot be accomplished with a simple load ...

Fig. 2b shows the complete gate-drive circuit for pulse transformer 2. The gate-drive circuits for the other three pulse transformers are the same. In some cases, ...
