Abstract
The utility mode relates to a commercial power and storage battery power supply switching circuit, which is mainly composed of commercial power, a storage battery, an AC/DC inverter, a DC/AC inverter, a controller, an alternating-current contactor JK1, and an alternating-current contactor JK2. The controller is connected with the storage battery, the AC/DC inverter, the alternating-current contactor JK1, and the alternating-current contactor JK2. The DC/AC inverter is connected with the storage battery. The commercial power is connected with the alternating-current contactor JK1. The alternating-current contactor JK2 is connected with a load. The alternating-current contactor JK1 and the alternating-current contactor JK2 employ an interlocking circuit. The switching circuit utilizes electric quantity in a power supply aging process to charge the storage battery and then the storage battery discharges to supply power to the load.
