Abstract
Abstract A system for driving a turbocharger (2) installed on an internal combustion engine (1) and combined with a rotary electric machine (3) which is mounted on a rotatable shaft of the turbocharger, includes a generator (4) drivable by output power of the engine. When the rotary electric machine (3) is driven as an electric motor, depending on an operating condition of the engine, electric power generated by the generator is supplied to the rotary electric machine through an inverter (5), under the control of a controller (6).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
100 words
A system for driving a turbocharger (2) installed on an internal combustion engine (1) and combined with a rotary electric machine (3), the system comprising: a rotary electric machine (3) mounted on a rotatable shaft (23) of a turbocharger (2); a generator (4) drivable by output power of the engine; means (6) for driving the rotary electric machine (3) as an electric motor depending on an operating condition of the engine; and means (5) for supplying electric power generated by the generator (4) to the rotary electric machine (3) when the rotary electric machine is driven as an electric motor.
Claim 2
Independent Claim
100 words
A system for driving a turbocharger (2) installed on an internal combustion engine (1) and combined with a rotary electric machine (3), the system comprising: a rotary electric machine (3) mounted on a rotatable shaft (23) of a turbocharger (2); a generator (4) drivable by output power of the engine; means (6) for driving the rotary electric machine (3) as an electric motor depending on an operating condition of the engine; and means (5) for supplying electric power generated by the generator (4) to the rotary electric machine (3) when the rotary electric machine is driven as an electric motor.
Claim 3
Dependent Claim
74 words
A system according to claim 1, wherein said rotary electric machine (3) comprises an AC machine, the means (5) for supplying electric power to the rotary electric machine having a rectifier for converting AC electric power generated by the generator (4) to DC electric power, and an inverter for converting the rectified DC electric power to AC electric power having a predetermined frequency and supplying the AC electric power to the rotary electric machine.
Claim 4
Dependent Claim
18 words
A system according to claim 2, wherein the rotary electric machine (3) comprises an induction rotary electric machine.
Claim 5
Dependent Claim
