Title: Control device for turbo charger with revolving armature
Inventor: KAWAMURA HIDEO
IPC: B60R16/04
Filed: 1988-04-06
Abstract: PURPOSE:To prevent the trouble due to the voltage reduction of a battery by providing the battery for a car mounted electrical instrument and the battery for driving a revolving armature and connecting the cable way of the battery to the revolving armature by switching it at charging time. CONSTITUTION:The battery 3 for a car mounted electric instrument and the battery 6 for driving the revolving armature fitted to a turbo charger 1 are provided. The flow of the power fed from the battery 3 into a power converter 8 is prevented by turning switches A, B OFF at the engine acceleration time. A revolving armature 2 is then accelerated by converting the DC power of the battery 6 into an AC power. The output voltage of the battery 3 has no effect therefore at the motor operation time of the revolving armature 2. Consequently the trouble due to the voltage reduction of the battery can be prevented.
