Abstract: A PFC circuit modulating a power line using pulse width modulation (PWM) to drive a power MOSFET and series inductor across the power line. Since many modern electronic systems include a power factor correction circuit (PFC) that already includes a series inductor and power MOSFET, a PLC is incorporated into a controller to inject a PLC transmit signal into a control loop for the PFC circuit. This can be done using either an analog PFC controller, such as the UCC28517, the UCC2819A, or a digital PFC controller such as based on a TMS320C24xx DSP.

Abstract: A method is disclosed for calibrating a position error signal (PES) to overcome the problem of an amplitude signal that varies as a non-linear function of real displacement when the read transducer is positioned to either side of a null position where the PES equals zero. The amplitude signal and resulting PES is notably nonlinear while reading servo burst information with a Magneto-Resistive (MR) head which has nonlinear magnetic characteristics. The calibration according to this method may be performed at anytime without need for real displacement information from a servo track writer or any sort of special calibration track. The method involves positioning the MR head to a plurality of nominal partial track displacements on either side of the null position, measuring an open loop gain value for a particular frequency at each of the displacements, deriving the coefficients of a 3.sup.rd order polynomial "gain" curve that best fits the data, integrating the "gain" curve using the coefficients to obtain a 4.sup.th order "position" curve, and then correcting subsequent measured displacements. If sufficient memory is available, the x, y values may be stored in a lookup table. The correction is preferably accomplished, however, by "inverting" the 4.sup.th order position curve through a process of establishing a plurality of "x, y" values, swapping the axes of such values, and then fitting a new polynomial to the transposed data.

Abstract: An apparatus and method for correcting for track misregistration when a slider or head assembly contains a separate read element and write element. The offset is determined at a first position and at a second position of the actuator arm assembly. From these offsets a constant and a multiplier are determined for determining an offset as a function of the cylinder location. Also disclosed is a method and apparatus for minimizing distance traveled to prevent misregistration when repositioning between the read element and a write element. The read element is intentionally offset from the write element at an angle so as to minimize the distance traveled across the disk.

Abstract: An apparatus for and method of automatically tuning a voltage regulation control loop for a digitally controlled switch mode power supply is provided. The method includes determining a frequency response of the power stage and calculating an open loop transfer function from the frequency response. A correlated metric is defined based at least in part on the open loop transfer function, wherein the correlated metric is correlated to an expected disturbance in regulated output voltage from the digitally controlled switch mode power supply due to a change in load. New values for the open loop transfer function are calculated for a range of controller compensation parameters to minimize the correlated metric. These values are then applied to the digital controller for use in controlling the power supply.
