Abstract
A voltage controller () operable to generate control signals for controlling an intermediate bus voltage (V) in an intermediate bus architecture power system (), the intermediate bus voltage comprising a voltage output from a first stage DC/DC power converter () to at least one second stage DC/DC power converter (-to-K). The voltage controller () comprises a receiver operable to receive at least one of voltage and current values input to the first stage DC/DC power converter (). The voltage controller () 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 () to set the intermediate bus voltage (V).
