QUASI RESONANT GATE CONTROLLER FOR A POWER DRIVER

摘要

A drive circuit for a power device includes a power transistor utilized to drive the power device. The drive circuit utilizes a resonant circuit that drives the power transistor at a high current level when the gate of the power transistor is in its Miller region. In one embodiment, the drive circuit includes dual transistors and an inductor tuned to the gate capacitance to drive the gate of the power transistor. The drive circuit may be useful in a variety of areas, such as with a valve controller for a camless engine.
