发明名称 Substation based high voltage uninterruptible power supply
摘要 A power supply includes an isolation transformer. The isolation transformer includes a primary winding and N secondary windings, where N is an integer. The primary winding receives a first alternating current voltage. Each of the N secondary windings generates a second alternating current voltage. M rectifiers convert the second alternating current voltages to a direct current voltage, where M is an integer. X inverters convert the direct current voltage to a third alternating current voltage, where X is an integer. A reference transformer is electrically coupled between the X inverters and output terminals of the power supply, is connected in parallel with the output terminals, and is configured to provide at least one of a neutral reference and a ground reference.
