Buck-Boost Regulator Circuit 5 V with 80% Efficiency *Ordered Premade*

DC Generator • Motor 2. 7 W • 24 V • 30 RPM

Battery with Battery Protection • 10, 000 m. Ah @ 5 V Outputs up 2 A Draws up to 1 A • Dimensions: 2. 9" x 1" x 4. 9" / 72 mm x 24 mm x 125 mm • Weight: 300 g • 80% Effecant

Simulation

Breadboard Proof of Concept • Used a Linear Regulator which is less then 50% efficient • Used a Hand Crank motor • Used a 3. 4 V Battery

PCB Board Design

PCB Product Ready to Be Ordered Top Bottom

Electrical Energy Harvesting Overview • Battery = Average 80% Efficiency • Buck-Boost = Average 85% Efficiency • Motors = 2. 7 W each = 5. 4 W at 30 RPM • 3. 456 W generation at 30 RPM • 691. 2 m. A generation at 5 V, at 30 RPM

Benefits to design • Easily can covert to AC Motor if Needed. • PCB Fits on top of the Buck-Boost Regulator therefore saving space. • Battery can be charged by a wall charger too. • Arduino boards and other electronics can also be power by battery therefore opening up further applications and not limiting it to phone charging.
