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

摘要： A voltage controller (700) operable to generate control signals for controlling an intermediate bus voltage (VIB) in an intermediate bus architecture power system (100), the intermediate bus voltage comprising a voltage output from a first stage DC/DC power converter (200) to at least one second stage DC/DC power converter (500-1 to 500-K). The voltage controller (700) comprises a receiver operable to receive at least one of voltage and current values input to the first stage DC/DC power converter (200). The voltage controller (700) further comprises a efficiency measuring unit operable to determine a measure of the efficiency of the intermediate bus architecture power system in accordance with the received values, and a control signal generator operable to generate control signals in dependence upon the determined efficiency measure to cause the first stage DC/DC converter (200) to set the intermediate bus voltage (VIB).
