Reactive Energy Compensator and Method for Reducing the Associated Flickering Phenomenon

A reactive energy compensator (10) comprising: an input DC voltage (Vc) bus (13) capable of providing reactive energy; an inverter (18) connected to the DC voltage bus (13) and including controllable electronic switches (34) capable of converting the input DC voltage (Vc) into an intermediate alternating voltage, a device (22) for controlling the electronic switches, regulation means (22) for determining a value of a target active current circulating between the inverter and the network, capable of regulating the input direct current voltage (Vc) relatively to a set reference value; the device for controlling the switches, determining control signals according to the value of said target active current, determined from the error between the reference value and the square of the DC voltage of the bus via a transfer function, the definition of which varies according to the current value of said DC voltage.
