Field coil fault detector for automotive alternator battery charging systems |
| abstract |
A detector monitoring the operational status of the field coil circuit in a multiphase alternator and voltage regulator battery charging system is disclosed. Circuit means monitor a first signal at a first terminal of the field coil circuit. Means generate sampling intervals on a repetitive basis. Circuit means interrupt the excitation signal supplied to the field coil by the voltage regulator during the sampling intervals. A second signal is measured during sampling intervals at a second terminal of the field coil circuit. Comparator means compare the first and second signals and produce an output signal when the comparison varies from a predetermined value. |
