Title: Alternator voltage regulator with relay - has wear of contacts reduced by using extra components
IPC: H02J7/22
Filed: 1973-05-24
Abstract: In alternator regulators as used to charge car batteries it is usual to detect the alternator voltage and at a preset level to open a relay to place a resistor in series with the exciting winding. Likewise, an extra high charging current can have the same effect. Because of the high self inductance of the excitation winding high voltages appear across the relay contacts causing arcing and material wear. This has been reduced in the past by using a diode(13) across the excitation winding(10), but power diodes do not act fast enough. This invention places a capacitance across the contacts to absorb the charge till the diode takes over, an inductor(24) (or resistor) is placed in series to limit the discharge currents when the contacts close again.
