Abstract
Disclosed herein is a regulator circuit for regulating the charging of a battery from a source of alternating current wherein the regulator circuit includes a rectifier having first and second pairs of terminals. Alternating current, applied to the first pair of terminals, is converted to a unidirectional charge current for application to the battery through the second pair of terminals. Circuitry, responsive to the voltage at the first pair of terminals, inhibits the generation of the charge current when the voltage at the first pair of terminals reaches a predetermined threshold. Additional circuitry, also responsive to the voltage at the first pair of terminals, provides a low impedence path across the second pair of terminals. Upon the occurrence of an overvoltage condition, the production of charge current by the rectifier is inhibited and any capacitance coupled to the charge current output circuit is discharged through the low impedence path provided across the second pair of terminals.
