Beschreibung
Zusammenfassung:	The apparatus includes a battery charger having a pair of input terminals adapted to be connected to an AC source of potential and a pair of output terminals adapted to be connected to the respective terminals of a battery. A rectifier converts the AC energy to DC. A series connected SCR is operable to connect the source with the battery when the battery potential is below a predetermined value. A reactance is provided to lower the source potential and to obtain substantially constant current for charging purposes. A shunt connected SCR is provided to limit the potential applied to the series SCR when the battery is charged to protect the battery and the series connected SCR.
