220V Wind Turbine Generator Circuit

220V Wind Turbine Generator Circuit changes wind energy to useable home power with 220V AC.

We need electricity every day so people try to get it free.

This simple small wind turbine is for home or low power use.

It cost less and give more electricity for the price.

This small wind turbine can power laptop, electric devices at home or outside.

12V wind turbine make power from wind and it is small and give alternate energy.

Wind power goes to bridge rectifier and controller and then battery charger circuit charge 12V 4.5Ah battery.

Step-up inverter make high voltage AC to run home appliances.

We can choose different 12V wind turbines with different watt power as per our need.

Bridge rectifier change AC to DC and in this circuit 1N4007 diode does this job.

Voltage regulator IC1 LM317 give output from 1.25V to 37V over 1.5A current.

Final DC from regulator goes to 12V 4.5Ah battery and this DC run the inverter circuit.

Formulas

Regulator Output:

LM317 regulator IC1 give output voltage:

Vout = 1.25V × [R2 / (R1 + 1)]

In circuit R2 means R2 + VR1.

Oscillator IC2 4047:

IC2 4047 is low power IC with 14 pins and work as multivibrator to make switching pulse.

Each output pin give 50% duty cycle.

Frequency formula at pin 13:

f = 1 / 8.8RC

here,

R = R4 + VR2 and C = C3

Frequency at pin 10, 11:

f = 1 / 4.4RC

where,

MOSFET & Switching:

Circuit use IRF540 N-channel power MOSFET by Vishay.

This MOSFET works at high temp with 175°C and fast switching.

Transformer:

Main part of wind turbine output is transformer:

230V primary 9V-0-9V 1.5A center tap secondary and is used in reverse.

MOV (metal oxide varistor) protect output devices.

Voltage Control:

IC1 LM317 get power from wind turbine and adjust output to 12V.

Battery connected through 1N5402 diode to get bias.

Working Process:

When ON/OFF switch is ON:

IC2 4047 work as astable multivibrator and the circuit start to oscillate.

Pin 10 and 11 give 50Hz to IRF540 MOSFET and the power goes to transformer secondary coil.

Output Behavior:

Current does not stay fixed all time it changes.

Coil make EMF (electromagnetic field) and this EMF changes the current.

Output voltage & frequency depend on:
