PROBLEM TO BE SOLVED: To provide a turbocharger power generating device having excellent followability to the load fluctuation in an internal combustion engine and capable of effectively and stably generating power.SOLUTION: A turbocharger power generating device (1) generates power by a power generater (7) by driving a gas turbine (3) and a compressor (6) by exhaust gas of an internal combustion engine (2). The AC power generated is supplied to a power system (12) via a power converting means (8). The power converting means (8) has a converter (13) converting the AC power to a DC power, a means (18) estimating a rotor rotation angle &thetas; based on a rotor magnetic flux, and a control means (15) coordinately converting the AC current to the DC current based on the rotor rotation angle &thetas; and controlling the output DC current power of the converter (13) such that the amplitude of the DC current is maintained in a target DC current value. |
