ABSTRACT:
A power switching apparatus for natural energy power supply includes a AC power supply provided by an electricity plant, a converting power supply connected with the AC power supply, a power switch connected with the converting power supply and an external load respectively, a charger connected with the power switch, at least a natural energy power supply connected with the charger, configured for generating electric power and supplying the electric power to the charger, a voltage sensor connected with the charger, and a battery pack connected with the voltage sensor. When there is not sufficient power output from the natural energy power supply, the AC power supply and the load are connected so that the object of uninterruptedly driving the load to work when the natural energy power supply stops working is achieved and the reliability of the natural energy power supply is improved.
