dear all, i need some help about current conditioning pass the comparator
here's the problem
i want to measure RPM data of AC generator (500W, 60 V) .
from P= V I we get I = 8.3 A
diagram block :
|generator output <sinusoidal wave>|---> |10 A bridge rectifier (fullwave DC)|---->|comparator <squarewave>| ----> |optocoupler<TTL output>|----> |counter|
do not find a comparator can handle that high current. please help
