1 Wind Turbine Thomas Grothe

2 Wind to Mechanical P wind = (1/2)ρ air Av 3 tip speed ratio = blade tip speed / wind speed Optimal tip speed ratio when t w = t s (this is when greatest possible amount of energy in the wind is used to rotate to rotor) t s = 2π/(nω) t w = x/v

4 Mechanical to AC Alternator uses induction to make 3-phase AC

5

6 AC to DC diode – allows current to go in only one direction

7

8 Battery apply a voltage that is higher than the battery’s output voltage charge controller puts extra current through something else industrial forklift batteries

9

10 120 V AC 60 Hz Output inverter – DC to AC
