Abstract

PURPOSE:To avoid the hindrance in the operation of inverter, by minimizing the overvoltage and voltage distortion at application, through the sequential application of invalid power supply device in synchronizing with the voltage phase of each phase in three-phase, in AC/DC conversion system. CONSTITUTION:A converter 3 is connected to an AC system via a main transfomer 2, an invalid power supply device 6 corresponding to each three-phase at the converter 3 of the main transformer 2 is provided, and an SCR switch 7 is provided so that the device 6 can be applied to corresponding interphase. Further, conduction control for each switch 7 is made by detecting the voltage phase between the phase corresponding to the line L, and each device 6 is sequentially switched synchronizingly between each phase of three-phase in the lines L.
