AUTOMATIC PORTABLE CHARGER

摘要

PURPOSE: An automatic portable charger is provided to charge a battery by using the inductive electromotive force generated from a motion of a permanent magnet within inductive coils. CONSTITUTION: An automatic portable charger includes a piezoelectric generation unit(100), a diode bridge circuit(200), a voltage stabilization circuit(300), a micro-charge circuit(400), and a cellular phone battery(500). The piezoelectric generation unit(100) includes a piezoelectric unit. The diode bridge circuit(200) is used for rectifying AC of the piezoelectric generation unit(100) to DC. The voltage stabilization circuit(300) is used for stabilizing the output voltage of the diode bridge circuit(200). The micro-charge circuit(400) is connected to the voltage stabilization circuit(300) in order to charge the cellular phone battery(500). The cellular phone battery(500) is connected to both ends of the micro-charge circuit(400).
