A three phase or single phase power supply come into
rectifier,now three phase or single phase supply is
converted into dc supply goes to battery charger and
simultaneously goes to inverter now the dc supply inverted

Off line ups a three or single phase power supply come into
rectifier the rectified dc supply goes to inverter...Un
fortunately main incoming supply break down time the battery
supply goes to inverter.....
