Reduce Changeover Time in UPS

by jeddy1515

In Industrial UPS as per IEEE standards after line goes your inverter should run load less than 5 ms. If we go with AC to DC and then applied to ADC it will take more than 10 ms which is not acceptable so that i used ADC sensing and by my algorithm i could judge interruption in line within 2 ms and effective stoppage at the load would be max 4 ms. In image blue graph is representing the line voltage at the load and as it is gone inverter supply represented by yellow one.
