Abstract: A turbocompressor apparatus includes a turbocompressor including a compressor motor, a lubrication pump including a pump motor, a converter that performs electric power conversion between a voltage of a power source and a direct-current voltage of a direct-current voltage unit in a case where electric power is being supplied from the power source to the turbocompressor apparatus; a first inverter that performs electric power conversion between the direct-current voltage and a first alternating-current voltage vector of the compressor motor; and a second inverter that performs electric power conversion between the direct-current voltage and a second alternating-current voltage vector of the pump motor. The compressor motor generates regenerative electric power by regenerative driving and the pump motor is driven by the regenerative electric power in a case where supply of electric power from the power source to the converter is being cut off.
