A hybrid turbocharger includes a first power conversion unit to convert a direct-current power into alternating-current power to be output to a generator motor, a smoothing capacitor between direct-current buses, and a control unit that controls the first power conversion unit so as to cause actual generator motor speed to comply with an engine speed command of the generator motor input from an upstream controller during a motoring operation of the generator motor. The control unit changes the engine speed command to a value which is equal to or greater than the actual generator motor speed if the engine speed command of the generator motor is less than the actual generator motor speed and a direct-current bus voltage is equal to or greater than a predetermined first threshold value during the motoring operation. Accordingly, the direct-current bus voltage can be prevented from increasing during the motoring operation.
