Abstract (en)
[origin: EP0326489A1] The regulation system consists of a current generator system (1) coupled to a pulse-width modulating converter (2). <??>The system includes means (11, 12) for sampling and measuring the voltage (V) and current (I) delivered by the current generator (1), a threshold detector (3) for detecting any maladjustment of the converter (2) which delivers a logic signal (C) representative of the maladjusted or non-maladjusted state of the converter (2) with respect to the threshold values. A control loop (4) consists of a switching element (42) which, by reversing the sign of the error signal ( epsilon ), enables the operating point to be returned to the point of maximum power (Pmax) on the output current-voltage characteristic of the current generator (1). <??>Application to the control of electrical power supply circuits in space installations. <IMAGE>
