Abstract
A gate driver of a power device includes an inductor and a supply. The inductor is configured to, during a transitional period of the power device, convert a potential on a gate to a field, and the field to an opposite potential to toggle the gate and charge a floating capacitor to the opposite potential as an excess field collapses. The supply is configured to maintain the gate at the potential and generate the excess field during a non-transitional period.
