Abstract
A reactive energy compensator is provided. The compensator is connected to an alternating electrical network including M phase(s), M being an integer greater than or equal to 1. The compensator includes M connection terminals, N banks of capacitor(s) capable of providing reactive energy, N being an integer greater than or equal to 2, N two-way voltage inverters, connected to each other in parallel and each connected to a unique capacitor bank, each inverter being able to convert a direct current into an alternating current including M phase(s) in one direction and the alternating current into direct current in the other direction, each inverter including first and second input terminals and M output terminal(s), the input terminals being connected to the corresponding capacitor bank, each output terminal corresponding to a phase of the alternating current and being connected to a corresponding connection terminal, and a device for balancing the voltage of the N capacitor banks.
