Current control via a variable voltage snubbing network

摘要

System and method for controlling current across a load. A preferred embodiment comprises a current varying circuit (such as current varying circuit 525 ) that can create a sequence of voltage drops in a driver circuit (such as the driver circuit 505 ) coupled to an inductive load (such as the inductive load 535 ). By initially producing a large voltage drop and then stepping the voltage drop down gradually, the current in the inductive load can be rapidly removed without producing a current undershoot, which, in certain applications, can result in unwanted noise and vibration.
