Pulsing DC voltage needs to be smoothed out with capacitors.

[WindyMarcus]

I have designed a wind turbine generator that creates AC voltage. The frequency and voltage vary as the wind speed changes. I use a full wave bridge rectifier to convert the voltage to DC. However this DC voltage is pulsing or not clean. (Sorry I know very little about this so forgive my incorrect use of terms.) Anyway, I understand I can use the correct capacitor to smooth a constant DC voltage and amperage. In my case the voltage and amperage is constantly changing. So I wonder is there a way to use multiple capacitors to smooth the mess and get a clean steady DC flow?
NOTES: The frequency on the AC ranges from zero to 50 kHz. After rectifying the DC voltage ranges from zero to 50. The amperage ranges from zero to 6.
Is there a way to sense voltage ranges such as 10-15 volts at .8 - 1.1 amp (for example) then use one capacitor to smooth that? Next sense the next level of voltage and switch to another capacitor? Is this the hard way to do it? I hope there is an easier way.
Since I am trying to create electricity I want to avoid losses as much as possible.
Would this solve the matter for me? If I run the DC voltage into a controller/charger (designed for this purpose to charge batteries) would it deal with the pulsing and charge a battery bank efficiently?

You don't need to use the exact capacitor calculated for any particular load. The result of using too large a capacitor is that it will stay charged longer and will take more current when it charges - so you can calculate for the worst-case (highest current load) and use that for everything.
