Hi, I've built a wind generator from a 99 volt low rpm DC motor. I'm trying to charge a 24 volt battery bank with it, along with some PV panels. I have an expensive inverter feeding 120v AC into my home, it is also capable of selling power back to the utility.
My project is to build a forward converter or boost converter of some sort to boost the voltage output of the wind genny X2. The reason is to get a 24 volt charge voltage(and hopefully current) sooner in the wind speed curve. Right now I get a solid 12 volts (o.c) at 10-15 MPH wind. I would like to double that to get some charge into the batts.
The circuit needs to be fairly robust to handle some charge current say 10 amps. Also it needs to have a fairly wide input voltage range say 0 to 20 volts DC. Any thing above 20 volts or so I could use a voltage limit of some kind (zener diode) to switch a relay and charge directly from the generator.The input is very wide ranging and the current requirements are ,potentially quite large. Not so much at low wind conditions though it could get cranking in high winds. The motor I'm using for a generator is capable of currents to 1kW I'm told. I'l probably never see it though.
Any thoughts on a circuit I could build to try this ? I can build my own PCBs and populate them. I cannot design it on my own.
Thanks in advance.
