PURPOSE:To work control and detecting signals among each inverter unit only by a multicore cable by installing input-output distribution circuits having relaying functions in control circuits at every unit. CONSTITUTION:When a power converter has a plurality of inverter circuits 3A, 3B, a control signal output from a control circuit 10 is input to an input- output distribution circuit 11B through multicore cables 13A, 13B, and further input to an input-output distribution circuit 11A through multicore cables 12A, 12B, control signals are transmitted over each inverter circuit 3A, 3B, and detecting signals from each detector 4A, 4B, 5, 6 are input to the control circuit 10 through the input-output distribution circuits 11A, 11B. Accordingly, each unit is mutually connected easily, and the power converter can also correspond to the change of specifications readily. |
