BATTERY CHARGING IN INTEGRATED-STARTER GENERATORS

Abstract:

An Integrated Starter-Generator (ISG) comprises a series regulator. The series regulator includes a controllable switch to be connected to a terminal of an electrical machine to receive an AC voltage from the electrical machine and to be connected to a battery to supply charging current to the battery in response to actuation of the controllable switch. The series regulator further includes a controller connected to the controllable switch to provide an actuating signal to actuate the controllable switch. The controller is configured to monitor a voltage level of the battery and determine whether to provide the actuating signal to the controllable switch based on the voltage level of the battery.
