PROBLEM TO BE SOLVED: To provide a technique for compensating back electromotive force voltage, related to the load of a switched type voltage mode power driver. SOLUTION: A power driver, for driving a signal on a load using a voltage mode driver, is provided. A system processor generates a commands for indicating a programmed drive signal that is desired from the voltage mode driver. A VBEMF compensator determines a compensated command for compensating for a back electromotive force voltage that is generated by a load. The compensated command is supplied to the voltage-mode driver, and the voltage-mode driver generates voltage output, based on the compensated command. |
