PURPOSE:To prevent reduction in efficiency at the partial load operation time by connecting a compressor to a turbine via a clutch, a motor to the compressor, a generator to the turbine. CONSTITUTION:A compressor 1 and a turbine 4 are connected to each other via a clutch 13. The compressor 1 and the turbine 4 are connected to a motor 12 and a generator 5, respectively. At the partial load time, the clutch 13 is disengaged to reduce the revolution speed of the turbine 4. Since the frequency is reduced, the power of the generator 5 is changed to direct current by a rectifier 6 and then the alternate current of the system frequency is regenerated by an inverter 7. The alternate current driving the motor 12 is generated by another inverter 11. The revolution speeds of both the compressor and the turbine 4 are reduced to reduce the air flow rate, so that the combustion temperature may be kept high and the efficiency reduction be prevented.
