Patent ID: 6897707

Claim:
A system for driving a gate of a semiconductor device, comprising: a switchable isolated voltage source providing a first input voltage level with a first input orientation and a second input voltage level with a second input orientation; a first current inhibiting element capable of inhibiting a first current flow having a first current orientation induced by the first input voltage level until a first predetermined voltage level is obtained across the first current inhibiting element; a first gate potential approximately equal to the first input voltage level minus the first predetermined voltage level; a second current inhibiting element capable of inhibiting a second current flow having a second current orientation, induced by the second input voltage level, until a second predetermined voltage level is obtained across a second current inhibiting element; a second gate potential approximately equal to the second input voltage level minus the second predetermined voltage level; and at least one of: a first asymmetric current inhibitor for flowing only a gate charge current, and a second asymmetric current inhibitor for flowing only a gate discharge current.
