NOVEL ARCHITECTURE OF A COMPENSATOR FOR POWER FACTORS AND HARMONICS FOR A POWER DISTRIBUTION NETWORK

摘要

The invention relates to a rectifier system for a primary AC electric power distribution network comprising a PFC circuit (11) connected to the primary network (12), which outputs DC power, and a means (14) for storing electric power connected to the outputs of the PFC via a switching circuit (16). Said circuit (16) is controlled either so as to discharge the electric power stored in the storage means (14) to the DC power supply line, or to charge the storage means (14) via the DC power supply line. A first control circuit (25) determines the operating status of the switching circuit by comparing the value of the voltage on the power supply line with a first reference voltage. A second control circuit (21) regulates the power output by the PFC to the power supply line, comparing the voltage (v) at the output of the storage means (14) with a second reference voltage. The two control circuits intersect. The system according to the invention can be used advantageously to respond to load requests without disrupting the primary network.
