hai,
presently am designing line measuring unit using PIC micro controller. in this am having shunt type step down unit which gives sinusoidal wave with respective to load current.so i interfaced with the controllers ADC section and try to get peak values and with some calculation(multiplication factor) i displayed the data .
here am struggling with the peak value getting function it gives the value +-5 ranges(495-500)for same load.so the output is not stable. can any one help me to get the current readings from sine wave of shunt type step down power measuring unit?
regards,
karthikeyan
