Summary:The embodiment of the invention provides a fully-controlled same-phase power supply system. The fully-controlled same-phase power supply system comprises a three-phase multi-winding split power transformer, a converter module and a single-phase three-winding boost transformer, wherein three iron core columns of the three-phase multi-winding split power transformer are all provided with n same low-voltage coils to form n three-phase low-voltage windings, the converter module comprises n power units which are cascaded, each power unit comprises a rectification unit, an energy storage filtering unit and an inversion unit which are sequentially connected, the three-phase low-voltage windings are inputs of the rectification filters, outputs of the inversion units are cascaded and then are output after boosting of the single-phase three-winding boost transformer, and the devices employed by the power units are mainly fully-controlled power electronic devices. The fully-controlled same-phasepower supply system provi
