The project is basically designed with Micro controller, ADC & on/off relays. The project maintains constant o/p respective of line & load variations. Here we r using voltage transformer to sense the o/p voltages. If the o/p voltage is greater than the predefined level the downward relay is in on state & the remaining two are in off state. If the o/p voltage is less than the predefined level, the up word relay is in on state, then the remaining two are it off state. If there is no change in the middle relay is at on state. The program is written in Micro controller , it reads the A.C voltage ,according to that the compensation relay operates in bug & boost modes. If the measured voltage is at beyond the limits, the o/p enters into the trip of state.
