Back electromotive force voltage compensation method for switched, voltage-mode driver circuit |
摘要 |
A power driver for driving a signal on a load using voltage-mode driver. A system processor generates commands indicating a programmed drive signal desired from the voltage-mode driver. A VBEMF compensator determines a compensated command to compensate for the back electromotive force voltage produced by the load. The compensated commands are coupled to the voltage-mode driver, such that the voltage-mode driver generates a voltage output based upon the compensated command.
