摘要： A power control system comprises a plurality of power control groups, with each group comprising a plurality of individual point-of-load regulators each adapted to provide respective regulated voltage outputs. The point-of-load regulators may be selected for inclusion in a power control groups based on characteristics of loads supplied by the point-of-load regulators. An intermediate bus controller is coupled to each of said power control groups through a serial data bus interface common to each group and an OK status line for each respective group. A front end regulator provides an intermediate bus voltage to each of the plurality of power control groups and to the intermediate bus controller. The plurality of point-of-load regulators of each group each further comprises a respective fault manager adapted to detect fault conditions and selectively communicate notifications of the fault conditions to other ones of the plurality of point-of-load regulators of the group and to the intermediate bus controller. This way, a common response to the fault conditions is taken by the point-of-load regulators of the group and other groups. A method for managing faults in the power control system is also disclosed.

摘要： A method and system is provided for optimizing the digital filter compensation coefficients of a digitally controlled switched mode power supply within a distributed power system. A power control system comprises at least one point-of-load (POL) regulator having a power conversion circuit adapted to convey power to a load and a digital controller coupled to the power conversion circuit though a feedback loop. The digital controller is adapted to provide a pulse width modulated control signal to the power switch responsive to a feedback measurement of an output of the power conversion circuit. The digital controller further comprises a digital filter having a transfer function defined by plural filter coefficients. The digital controller periodically stores a successive one of a plurality of samples of the feedback measurement. A serial data bus operatively connects the POL regulator to a system controller. The system controller retrieves each successive stored sample from the digital controller via the serial data bus. After retrieving a pre-determined number of the samples, the system controller calculates optimized filter coefficients for the digital filter and communicates the optimized filter coefficients to the digital controller. The digital controller thereafter uses the optimized filter coefficients in the digital filter.

摘要： A power supply comprises at least one power switch adapted to convey power between input and output terminals of the power supply, and a digital controller adapted to control operation of the at least one power switch responsive to an output measurement of the power supply. The digital controller comprises an analog-to-digital converter providing a digital error signal representing a voltage difference between the output measurement and a reference value, a digital filter providing a digital control output based on a sum of previous error signals and previous control outputs, an error controller adapted to modify operation of the digital filter upon an error condition, and a digital pulse width modulator providing a control signal to the power switch having a pulse width corresponding to the digital control output. The analog-to-digital converter further comprises a windowed flash analog-to-digital converter having a transfer function defining a relationship between the voltage difference and corresponding digital values. The transfer function provides a substantially linear region at a center of a corresponding error window, including a first step size in the center of the error window and at least one other step size in a peripheral region of the error window that is larger than the first step size. The first step size and the other step sizes may each reflect a linear relationship between the voltage difference and the corresponding digital values. Alternatively, the first step size reflects a linear relationship between the voltage difference and the corresponding digital values, and the other step sizes each reflect a non-linear relationship between the voltage difference and the corresponding digital values.

摘要： A pulse width modulation system for use in a switching power supply circuit provides high-resolution pulse width modulated signals. The pulse width modulation system is configured to receive a control signal comprising a (m+n)-bit binary word and to provide a pulse width modulated signal with a predetermined average duty cycle having a resolution of substantially 2−(m+n). The pulse width modulation system includes a timing circuit for providing 2m timing signals, a dithering circuit, and a signal generator. Upon receiving the control signal, the dithering circuit is configured to provide a modified control signal, which comprises a series of up to 2n m-bit binary words. The signal generator is configured to receive the timing signals and the modified control signal and to provide the pulse width modulated signal having a duty cycle, which, when averaged over 2n timing cycles, is approximately equal to the predetermined average duty cycle. The pulse width modulated signal is used by a switching power supply circuit to control at least one power switching device.

摘要： A system and method is provided for determining a voltage output of a programmable power converter based on programming voltage data received from one of a variety of alternate sources. Specifically, in one embodiment of the present invention, a control unit is adapted to monitor a digital data serial interface, a digital data parallel interface, and an analog data interface to determine whether programming voltage data has been received. If programming voltage data has been received, the data is used to determine an output voltage for the programmable power converter. If more than one set of programming voltage data has been received, a determination is made as to which set of data takes priority. The selected set of data is then used to determine an output voltage for the programmable power converter.
