Optimization of an Energy Recovery Circuit for a Low-Voltage Lighting System

This work is devoted to the study of the physical properties of a circuit that allows both the last remaining charges of a pile or a accumulator yes cells unique to be used in other devices and to save energy stored in a new battery and all this in the lighting domain . The corresponding device is made from a transistor, a resistor and a coil. The coil is made up of a standard ferrite core with two windings of which the primary contains 34 turns and the secondary, 58 turns. Most components are local components. The study is based on the Proteus simulation software. The experiment of the device consists of comparisons of the energy consumed by an electroluminescent diode without the designed circuit and with this circuit to see its performance. In particular, the circuit can use a very low voltage of about 0.37V and can power the electroluminescent diode for a week without interruption if it is powered by a R6S/1.5V battery.
