摘要： A hybrid turbocharger includes a first power conversion unit to convert 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.

摘要： A control unit (40) controls a first power converter so as to make the speed of a motor/generator coincide with a prescribed speed command. A speed command (N*) set by an upper stream control system (50) is inputted to a smoothing unit (41) of the control unit (40). In the smoothing unit (41), the speed command (N*) is smoothed by a first-order lag element (46), and the rate of change is limited by a rate limiter (48) to a prescribed value or less. For the speed command (Ns*) outputted from the smoothing unit (41), the difference (ΔN) from the actual speed (N) of the motor/generator is calculated in a difference calculator, a control command (S) based on this difference (ΔN) is generated in a control signal generator (43), and the first power converter is controlled on the basis of this control command (S). Fluctuations in the supply of power to the electric motor are thereby suppressed.

摘要： A supercharging system includes: a first supercharger including a first compressor for compressing air to be supplied to an engine and a motor for driving the first compressor; a leakage current measuring part for measuring a leakage current of the motor; and a first controller for controlling the first supercharger. The first controller includes a motor control part configured to, when a measurement result by the leakage current measuring part is not less than a first threshold, set an upper limit value of an output command value for the motor to be lower than when the measurement result is less than the first threshold, and to control an output of the motor within a range which does not exceed the upper limit value.
