Abstract

PURPOSE:One DC constant-voltage control circuit is used in common; and with change-over of interlocking switch, power supply is performed from AC to load, electric charge is carried out for incorporated battery, and power supply is performed from battery to load. At the same time, the protection for the whole circuits can also be ensured.
