FIELD: control devices.
SUBSTANCE: present invention relates to a control device for a series multiplex inverter capable of outputting voltage through inverters, and in particular relates to loss equalization control.The high level control unit (5) generates an L* level command based on the cmd command value. The switching load distribution control unit (6) stores information about the period of the output state of each cell and assigns a control signal so that: in the case of a scheme according to which the cell changes from level level ±1 is set to level 0; and in the case of a scheme in which a cell changes from level 0 to level ±1, the cell having the longest period of the output state with level 0 is set to level ±1.
EFFECT: improving the distribution of the switching load level in each cell in the control device of the serial multiplex inverter.
