3. I NTRODUCTION The project is a wind belt generator that will be used to charge a modern cell phone battery. Requirements//Components: Wind: Energy source which cause oscillation. Magnets: Excite Coils/Faraday’s Law. Coils: Induces a magnetic field, that causes charge at the load. Membrane: Moves magnets to change magnetic field causing voltage. Rectifier: ADC converter. Battery: Load, and holds charge.

9. R ECTIFIER Using four matched diodes with pairs of diodes oriented in opposite directions. Aiming to create a DC signal using an AC signal as an input. When the input signal changes from positive input to negative input, the output signal is only within the positive plane. The figure below demonstrates the orientation of the diodes. Figure 2. Bridge Rectifier

10. T HE FRAME PVC plastic piping will be used for its rigidity. Metal won’t be used for the fear that it would negatively affect the magnets and the magnetic flux.

11. T HE F RAME

12. R ECTIFIER MINIMUM INPUT VOLTAGE = 0.74 V using the function generator, the necessary voltage to turn on the rectifier in the forward active regime is 0.74 V

13. I SSUES / CONCERNS Frame size for oscillation. Time to charge the battery. (may take a long time to charge) Might blow the battery.
