Hi All,
I am building a wind generator to charge a 12v bank of batteries and I am stuck on the design of one of the circuits i am going to use. Actually its not the design as much as its the selection of components and values... I am setting up the system like this Turbine -> Voltage Tripler -> Voltage Regulator -> Charge Controller -> Battery Bank -> Inverter.
I have tested the turbine and estimate it will produce 1 - 6 amps and 1 - 11volts(before the tripler). The circuit that i am having difficulty designing is the Voltage Regulator because it will have variable voltage and current to the input. The output will go to the batteries which require approximately 14V to charge, the current is not a concern because the Charge Controller will prevent over charging and the tripler will keep the current reasonably low.
I have researched some components and http://pdf1.alldatasheet.com/datasheet-pdf/view/56777/BURR-BROWN/OPA501AM.html seems to be my best bet for the opamp. But as for the other components such as the transistor, zener diode and resistor values i am not sure what to use??? its been a few years since i have done any circuit design, the tracing of current and such came back pretty quick but with selecting values I am still lost ...
Here is the circuit i am going to use, a pretty basic voltage stabilizer where the operational amplifier opens the transistor more if the voltage at its inverting input drops significantly below the output of the voltage reference at the non-inverting input. R1 and D2 will set the Voltage reference, R2, R3, R4 will set the output voltage between D2 and Input.
Thanks,
Ken
