The objective of the present invention is to reduce the manufacturing costs of an electric power converting device and to reduce the installation space thereof. An electric power converting device comprises: AC/DC converters and AC/DC converters connected in series to an alternating-current power supply; direct-current buses provided on an output side; change-over switches, change-over switches, change-over switches, and change-over switches for selectively connecting the AC/DC converters and the AC/DC converters to each direct-current path; a bus-to-bus connecting switch connecting the direct-current buses in series; and a switch for connecting an electric circuit connected in series by means of the bus-to-bus connecting switch to a load.
