The output voltage of a permanent magnet alternator depends on the shaft rpm and the load. The higher the rpm, the higher is the voltage. The higher the load for a given rpm, the lower is the voltage. Connection to Current and RPM o Load The current (“amperage”) of a dc...
In marine environments where the sources of electricity are scarce, batteries are the only viable option and due to high wind speed at sea, these wind turbine battery charging options become a very profitable and convenient source. The overall cost of electricity is reduced. Also with battery usage the...
The market for small wind turbines is providing added electrification needed in remote areas. Many parts of the world are still running on electricity from batteries rather than electrical grids laid by national power corporations. Telecom companies who have to provide uninterrupted signals in remote areas rely on batteries...
Still many considerations are to be taken into account to get the desired efficiency. If the rotor speed is low i.e if the frequency is low then a larger construction is required which increases the overall cost. Hence newer designs are required which increases the efficiency along with smaller...
Wave energy and tidal power have always been an area of interest in many nations since there is an immense potential in these energy sources but the problem of energy conversion has always been a daunting issue. The traditional energy conversion devices use rotary generators which are high speed...
10kW Generator in Telecom During past seven years the installation of telecom grids all over the world has increased many folds. During these competitive times, the telecom companies are expanding their networks to regions where there are no electric grids also. The small wind industry is a key player in...
10kW Design The 10kW permanent magnet generator finds its applications in residential houses on country sides, farming sites, small business setups etc. This has empowered owners to a great extent to reduce utility bills. Other than these, 10kW wind turbine setups are very famous in telecom sector, on or off...
Example of Maximum Power Point Tracking Imagine a conventional controller (non MPPT) that connects the alternator (75W) to the battery (12V) to charge a discharged battery. This makes the permanent magnet alternator operate at the battery voltage which may not be the ideal voltage at which the module is...
Maximum Power Point Tracking or MPPT is an electronic system that allows grid tie inverters and battery chargers to get maximum power from the electricity source. These sources can be solar panels or other renewable sources like wind that is used by permanent magnet alternators. MPPT is a technique through...
Wind energy companies seek to develop more and more operational wind energy projects and farms every year. Many nations have now pledged to get a major portion of their power from renewable sources of energy like wind, water etc. but funds for these projects are huge and large companies...
