1. A regulator for regulating the charging of a battery from a source of alternating current, said regulator comprising rectifier means having a first pair of terminals and a second pair of terminals and operable for converting alternating current applied to said first pair of terminals to a unidirectional charge current and for applying the charge current to the battery through said second pair of terminals, first means responsive to voltage between said first pair of terminals for substantially removing the charge current from said second pair of terminals when the voltage between said first pair of terminals reaches a predetermined threshold, and second means responsive to the voltage between said first pair of terminals for providing a low impedance path between said second pair of terminals upon the voltage between said first pair of terminals reaching a predetermined threshold.
