Abstract
A solar array system includes at least one solar array and at least one solar array regulator. The solar array regulator has an input port to be connected to the solar array, and an output port to be connected to a power bus. The solar array comprises a switching voltage converter comprising a step-down (PC) and a step-up (PC) power cell connected in cascade; and a control circuit for driving said voltage converter in a step-up, a step-down or a direct energy transfer mode, depending on an input control signal and on at least one feedback signal (S) indicative of an operating condition of said switching voltage converter; characterized in that said at least one feedback signal (S) is indicative of an intensity of an electrical current (I) flowing between said step-down and said step-up power cells, whereby the control circuit implements an internal current feedback control.
