Abstract

PURPOSE: To prevent the variation of the current of motors, by connecting a switch operating at the final stages of series stage in sereies with a diode while replacing a switch operating at the final stage of series or parallel stages with other diode, in a device that changes over and connects a plurality of drive motors in series or parallel.
