![]() The zener diode at the base of T2 decides the regulation level and can be selected as per the required load restrictions specs. The output from the windmill is suitably rectified by the associated bridge rectifier network and fed to the IC 555 based boost rectifier circuit.Īssuming the average windmill motor output to be around 12V, the boost circuit can be expected to boost this voltage to upto 60V+, however T2 stage in the circuit is designed to restrict this voltage to a specified stabilized output. ![]() ![]() The above image shows a simple boost converter circuit with a feedback error amplifier regulator stage. The following image explains the details of the involved circuits, which are also not so complex and may be built using most of the ordinary components. In the diagram we can seen a boost converter being employed after rectifying the windmill electricity through a bridge rectifier network. We can solve the issue by adding a boost or a buck converter circuit as per the specs of the connected load.īut if your motor voltage specs is slightly higher than the load and if there's ample wind, you may exclude the involved boost circuit and directly connect the windmill output with the load after the bridge rectifier. However, since the wind speeds could be fluctuating and never constant, it may be imperative to include some kind of stabilizer circuit across the output of the motor. The electricity generated by the rotation of the motor coil in response to the torque from the turbine can be used for charging a battery or may be for driving an LEd lamp or any desired electrical load as per the user preference. Integrating an Electronic voltage Regulator In the shown concept the motor connected with the turbine keeps rotating with maximum efficiency no matter from which side or corner the wind may be appearing, which allows the windmill to be extremely effective and active all through the year. In this design the turbine rotation does not rely on the wind directions rather responds equally well and efficiently regardless from which side the wind may be flowing, this allow the system to get rid of a complex rudder mechanism, which are normally used in conventional windmills in order to keep the propeller self adjusting its front position in line with the wind flow. Here a twisted "S" shaped propeller system is used which has a distinct advantage over the traditional airplane type of propeller. The principle of operation is based on a traditional motor generator concept where a permanent magnet type motor's spindle is integrated with a turbine or propeller mechanism for the required harnessing of wind power.Īs may be seen in the above diagram, the employed propeller or the turbine structure looks different. Designing a Windmill GeneratorĪ simple windmill generator circuit concept presented here can be built by any hobbyist for charging small batteries at home, completely free of cost and with negligible efforts.īigger models of the same can be tried for achieving greater power outputs which may be used for powering small houses. It's said that over 100 meters from ground wind speeds are the maximum and it's active all through the year non-stop, so that proves, higher the altitude better the wind efficiency. ![]() However a windmill generator may work with greatest efficiency only if it's installed or positioned on specific regions such as on higher altitudes, near sea or river shores etc.įor a homemade windmill generator to be most efficient one must position it on the roof top of the house in order to get the highest possible wind speed efficiency, the higher the better. Furthermore, the sun light being at its peak only during midday and not throughout the day makes its harnessing very inefficient.Contrary to this a windmill generator which depends on wind power appears to be much efficient because wind is available all through the day and does not rely on seasonal changes. One of the biggest drawback of solar panel electricity is that it's available only during the day time and that too only when the sky is clear.
