Abstract

A solar array regulator (SAR) having an input port to be connected to a solar array (SA), and an output port to be connected to a power bus (PB), comprising a switching voltage converter (SVC) comprising a step- down (PC1) and a step-up (PC2) power cell connected in cascade; and a control circuit (CC) for driving said voltage converter in a step-up, a step-down or a direct energy transfer mode, depending on an input control signal (PSR) and on at least one feedback signal (SIL F) indicative of an operating condition of said switching voltage converter; characterized in that said at least one feedback signal (SIL F) is indicative of an intensity of an electrical current (IL) flowing between said step-down and said step-up power cells, whereby the control circuit implements an internal current feedback control. A solar power system comprising: at least one such solar array regulator; at least one solar array (SA) connected to the input ports of said or each solar array regulator; and a power bus (PB) connected to the output ports of said or each solar array regulator.
