摘要

The system static power conversion of the electric network single-phase three-phase four wire in the electric network and method for compensation of stress amplitude. The present invention is situated in the fields of electrical engineering and automation and control system, and describes a static p For conversion of electrical energy in three-phase four wire single-phase grounding of the neutral conductor.Specifically, the present invention includes a static converter power associated with parallel to the single-phase network to produce, in conjunction with the direct feed of the network, a power supply consists of three stages in addition to a neutral grounded. The static converter in parallel, with a dedicated control system, allows compensation of voltage and power factor correction.The system maintains the reliability for the loads connected in the terminal phase in case of any damage to the whole single-phase three-phase converter - because it is not inserted any element in series with the original single-phase network.It is also possible to connect sources of alternative energy and / or set by the system, limit the output current and to adjust the tension in the current link remains, in addition to regulate the output voltage of the three-phase and regulate or to correct the power factor of the input voltage ADA monophasic.The present invention also describes a method for the compensation of the amplitude voltage of single-phase input terminal.
