Abstract
PURPOSE:To enable to prevent a DC overvoltage at the time of starting an AC/DC converter by starting after confirming that the converters except the converter initially started of a plurality of converters connected in series are in all bypass pair state. CONSTITUTION:The converter is started after confirming that the converters except the converter initially started of a plurality of converters connected in series are in all bypass pair state (BPP). For instance, a circuit shown in a drawing is provided between the respective controllers 11, 12 of two power rectifiers connected in series and gate signal generators 13, 14. When a deblock command of one converter is, for example, generated so that the output of the controller 12 becomes ''1'' and the output of the controller 11 becomes ''0'', the output of an element 17 becomes ''1'', a BPP signal is fed to the generator 13 through a pulse transformer 26, and the BPP operation is conducted. When this signal is returned through a pulse transformer 27, the output of an element 18 becomes ''1'', the signal is fed through an element 24 to the generator 14, and the corresponding converter is deblocked.
