    摘要: A controller (500) for determining a distribution of switching phases among switching elements of a power supply system The power supply system has a plurality of voltage converters, each comprising a switching element and being arranged to convert an input voltage supplied to the voltage converters to a respective output voltage by switching the switching element at a predetermined frequency. The controller (500) comprises a receiver (510) for receiving one or more signals indicative of a respective contribution from each of the voltage converters to a ripple voltage component of an input current of the voltage converters, and a rank determining module (520) configured to rank the voltage converters in order of decreasing contribution to the ripple voltage. The controller (500) further comprises a switching phase offset calculator (530) configured to calculate a respective switching phase offset that is to be applied for the switching element in each of the voltage converters by: (i) calculating respective phase offsets of the two highest ranked voltage converters that would minimise an input voltage ripple caused only by said two highest ranked voltage converters; (ii) calculating a phase offset of the next-highest ranked voltage converter that would minimise an input voltage ripple caused only by said next-highest ranked voltage converter and the voltage converters ranked higher than said next-highest voltage converter; and (iii) repeating step (ii) for each subsequent voltage converter in the ranking. The controller (500) also includes an output signal generator (540) configured to generate one or more output signals defining the calculated switching phase offsets to be applied to the switching of the respective switching elements.

    摘要: Method determines a configuration of capacitors in an output filter of a switched mode power supply (SMPS). Candidate configurations are generated, each associated with a respective cost function value calculated based on number of capacitors of each kind in the candidate configuration and cost assigned to each kind of capacitor. The candidate configurations are ordered based on their cost function values. A binary search through the ordered candidate configurations determines a capacitor configuration associated with a lowest cost function value to allow a defined load transient response requirement of the SMPS. Whether a candidate configuration allows the defined load transient response requirement of the SMPS is determined using a model of a SMPS having the candidate configuration of the output filter simulating deviation of output voltage of the SMPS in response to change in load current of the SMPS and determining whether the defined load transient response requirement is allowed.
