description The utility model, which belongs to the high-voltage converter field, discloses an SVG apparatus based on split-phase control. The SVG apparatus comprises an SVG power cabinet and a main controller; the SVG power cabinet is provided with a plurality of built-in power modules in series connection; and the main controller is connected with the SVG power cabinet. A split-phase controller is installed at an insulated side plate inside the SVG power cabinet. Each power module in the SVG power cabinet is connected with a drive plate that is used for issuing an instruction to the power module and uploading drive plate information to the split-phase controller; and the drive plates are in communication connection with the split-phase controller by optical fibers. The split-phase controller takes power from one power module and is connected with the main controller for communication by two high-speed optical fibers. According to the technical scheme, the optical fiber usage is substantially saved; the optical fiber wiring becomes convenient and rapid; and the maintenance can be carried out conveniently. The split-phase controller can use any power module for power supplying and thus no extra power supply is needed, so that the production cost of the SVG apparatus is lowered and installation and maintenance become convenient.
