Abstract
A single active element performs the multiple functions of regulating DC voltage level from an AC source supplied to charge a battery and of coupling the battery to power an emergency system such as an emergency lighting system upon loss of the AC source. Preferably, the single active element also performs a third function of disconnecting the battery from the emergency system in time to prevent over discharge and consequent permanent damage to the battery.
