Questions & Answers
Right now key questions to answer are (lets append the answers alongwith as we find them)
- what is cause of low efficiencies in UIUC design. Is that MOSFET? poor design? could they not catch it in pspice simulation they carried out before the design?
- Are there theoretical benefits of higher voltage? There are conflicting opinions on this, as Hugh Piggot thinks R will increase as square of voltage, nullifying the benefits, while some others think it is good idea. Can we analyze this more carefully to get a final answer?
Some not so key questions are
- saurabh: what not do ac-ac stepdown by transformer? more losses?
- ameet: what is Michael using currently to down convert 48V to 12V? I did not see any converter in the schematic. I just saw charge controller for one of the batteries. Rest of 4 batteries were connected in series tto make 48V.
- ameet:How does generator voltage stay constant at 48V? does it not fluctuate with wind speed? Answer should lie in Hugh's Wind Turbine handbook.
- rathna: what efficiencies will make the converter more attractive than current setup?e.g. If we are saving 15W in input side losses, and lose those in converter losses, we better not use it :-)
