Wind turbine generator output voltage is directly fed into LM317 positive Regulator circuit and it is adjusted to give 12 volt output and Battery connected to this bias through (3A, 50V) Schottky diode. MOV (Metal oxide Varistor) protects electronic device connected at output. Main part of wind turbine generator is output stage, here transformer X1 is used in reverse with specifications as 230V primary, 9V-0-9V / 1.5A secondary winding center tapped transformer. It gives fast switching, and have high operating temperature characteristics (175✬). #Small home wind turbine driversIRF540 N Channel power mosfet from vishay siliconix used as a switching drivers for this inverter circuit. For pin 10 and 11 the formula changes as f=1/4.4RC. by using this formula we can obtain frequency output at pin 13. It provides full Oscillation output F at Pin 13, 1/2 of oscillation at Pin 10 as Q and Pin 11 as Q’. Monostable / Astable multivibrator IC CD4047 used here to produce switching pulse, This IC works in low power and available in 14 pin Dual in line package. Inverter Circuit using IC CD4047 (Switching Pulse Oscillator) Regulator LM317 output voltage Vout can be obtained as final output from the regulator is given to 12/4.5Ah SLA Battery, this Battery provides DC bias to the inverter circuit. The LM317 adjustable three terminal Positive voltage Regulator used here and it can give output voltage range from 1.25 V to 37 V with more than 1.5A current rating. We know the bridge rectifier converts AC supply into DC and here we used 1N4007 diode as a bridge rectifier element, it converts the energy from wind turbine into Direct Current (DC) supply.
