。[Claims for Utility Model Registration] A single converter unit that converts AC power into DC power, and inversely converts the converted DC power to AC power of a predetermined frequency, and AC power that is inversely converted to multiple electric motors. A power conversion control device for electric motor utilization equipment having a plurality of inverter sections provided for each electric motor for supplying power, wherein the power capacity of the converter section is the sum of the power capacities of the plurality of inverter sections. The power capacity of the converter section is smaller than that of the inverter section to which the maximum load is applied, and is larger than the power capacity of the inverter section to which the maximum load is applied. A power conversion control device for equipment using an electric motor, comprising an operation controller that issues a power supply command to each of the inverter sections within a power capacity range.
