The voltages range from 0 to 50VAC at the maximum wind speed ever recorded. This passes via a bridge diode rectifier which in turn feeds it into my 12V battery. The problem is that higher wind speed produce high voltages which kill my battery after some time, I have been trying to regulate the voltage after the rectifier to 15VDC using many LM7815 regulators in parallel but they waste too much energy in heating so I thought of using a pulse widith modulation circuit to do the voltage regulation because with PWM there is little energy wasted as heat. It is for this reason that I would beg any body who knows any circuit that can regulate or stablise the high voltage of my wind generator at high wind speeds to 15VDC using PWM technology, please send it to me.
