Abstract
A junction device driver is provided that includes a current regulator, an inductor coupled with the current regulator, and a switching module coupled with the inductor. The current regulator is configured to generate a current, and the inductor is configured to store energy generated by the current produced by the current regulator. The switching module is configured to control a conduction current for a gate of a junction device. The conduction current is generated, initially, from the stored energy of the inductor to thereby provide a relatively high initial current. As the energy stored in the inductor is discharged, the current level drops to a lower level that is sufficient to maintain the junction device in an “on” state.
