Abstract
An input voltage transfer apparatus for an LED lighting system is provided. The input voltage transfer apparatus includes a source voltage storage unit, a zero voltage switching unit, and a nonzero voltage switching unit. The source voltage storage unit stores a source voltage. The zero voltage switching unit turns on according to the source voltage stored in the source voltage storage unit when a zero voltage is inputted. The nonzero voltage switching unit turns on according to a current applied thereto through the zero voltage switching unit when a nonzero voltage is inputted. When the nonzero voltage switching unit is turned on, the source voltage storage unit discharges the stored source voltage.
