摘要： A switched mode power supply (SMPS) comprising a feedback unit, voltage feed forward (VFF) compensation signal generator and a transient detector. A VFF compensation signal is only applied to the output of the feedback unit when a transient is detected by the transient detector on the input voltage of the SMPS, thereby saving power and computation time. The transient detector comprises a first comparator to detect that a positive transient has occurred if a difference signal is greater than a positive threshold level; a second comparator to determine if the difference signal is within a predetermined range of positive values and output a result that indicates if the difference signal is within the predetermined range of positive values; and a first calculator to detect that a positive transient has occurred if, out of a first predetermined number of consecutive results of the output of the second comparator, there is at least a second predetermined number of results indicating that the difference signal is within the predetermined range of positive values. The transient detector comprises further features for similarly detecting a negative transient.

摘要： A method of determining a measure of a total capacitance of one or more capacitive elements connected to an output of a switched mode power supply is described. The method includes generating a voltage control signal to cause an output voltage control signal age controller to sweep a voltage at the output of the switched mode power supply from an initial voltage value to a final voltage value. Sample values of a current at the output measured by a current sampler during the sweep of the output voltage are received, and an integrated current value representing a measure of the total capacitance using the received sample values is calculated.

摘要： A method of determining a current in a switched mode power supply. The method comprises: storing values representing at least one pre-calculated matrix A; receiving measured current values; and using the stored values representing the matrix A and the received current values to calculate a respective initial value for each of the coefficients of the line and for each measured current value: calculating an estimated current using the equation of the line and the calculated initial values of the coefficients; determining a difference between the measured current value and the estimated current value to generate a difference value, and comparing the difference value against a threshold and, if the difference value is greater than the threshold, calculating updated values of the coefficients using stored values representing matrix A and difference value. A value for the current in the switched mode power supply is determined using the updated values of the coefficients
