MONITORING CIRCUIT FOR CONTROL MEANS AND SELECTIVE BREAKAWAY MEANS IN MODULAR SUPPLY SYSTEMS

摘要

Modular supply systems are usually constituted by a plurality of n elementary power units, connected in parallel each to the other, and to each of which control (RV) and selective breakaway means (DS) are associated. The monitoring circuit (CP) is constituted by first means (PM) which calculate the entity of the deviation (E) between a signal (Iui) that is proportional to the current supplied by its relevant power unit (UAi) and a signal (Imed) that is proportional to the average value of the currents supplied by the n power units, as well as by second means (SM) which algebraically sum said deviation (E) to a signal (Vui) proportional to the voltage available on the output of its relevant power unit. The signal (Vc) available on the output of the second means is delivered to said control (RV) and said selective breakaway means (DS).
