Latest Patents

Gene Plutowski holds a patent titled "Efficient transition from class D to linear operation in dual-mode voice coil motor controllers." This patent describes a dual-mode positioning driver for a voice coil motor in a disk drive system. The invention features linear prestage drivers and pulse-width-modulated prestage drivers that are coupled to power transistors arranged in an 'H' bridge. This configuration allows the positioning driver to operate in either a linear mode or a pulse-width-modulated class D mode. During the transition from pulse-width-modulated mode to linear mode, comparators compare the phase voltages in the 'H' bridge with a reference voltage. The outputs of these comparators are applied to the PWM output amplifiers to drive the power transistors, minimizing discontinuities in the drive current through the voice coil motor.
