Beschreibung
Zusammenfassung:	A transformer-based battery charging circuit and method for reducing heat generated by the circuit during inactive periods uses a light emitting device, which is electrically connected to the secondary winding of a transformer, and a light-dependent resistor, which is electrically connected to the primary winding of the transformer, to decrease the current conducted through the primary winding of the transformer during the inactive periods.
