Abstract
A system for regulating the operating point of a direct current power supply comprising a current generator system connected to a pulse width modulation converter includes a circuit for sampling and measuring the voltage and the current supplied by the current generator. A threshold detector circuit responding to stalling of the converter supplies a logic signal representing the stalled or non-stalled state of the converter relative to threshold values. A regulation loop includes a switching device for inverting the sign of the error signal so that the operating point can be moved towards the maximum power point on the output current-voltage characteristic of the current generator. The system is applicable to regulation of the electrical power supply circuits of spacecraft, space probes, satellites and the like.
