Abstract:
1. A voltage controller operable to generate control signals for controlling an intermediate bus voltage (V IB ) in an intermediate bus architecture power system, the intermediate bus voltage comprising a voltage output from a first stage DC-to-DC power converter to at least one second stage DC-to-DC power converter via an intermediate voltage bus in the intermediate bus architecture power system, the voltage controller comprising: a receiver operable to receive in a first iteration and a next iteration subsequent to the first iteration, measured values of current input to the first stage DC-to-DC power converter or current and voltage output by the first stage DC-to-DC power converter; an efficiency measuring unit operable to determine a measure of an efficiency of the intermediate bus architecture power system in accordance with the received values, said efficiency measuring unit being operable to: a control signal generator operable to generate control signals to cause the first stage DC-to-DC converter to set the intermediate bus voltage (V
