Abstract
A rapid switching emergency power supply comprises a first static switch connected to a main line. One end of the main line is connected to a power supply input terminal and the other end is connected to a power supply output terminal. The main line is connected in parallel to a spare line. A stand-by power supply, an inverter and a second static switch are successively connected in series to the spare line from the power supply input terminal to the power supply output terminal. A controller is also arranged. The controller is connected with the first static switch, the second static switch, the inverter, the main line and the spare line. When power supply of the power supply input terminal is normal, power is provided for a load through the first static switch and the stand-by power supply is charged. When the power supply has a fault, the controller makes the first static switch rapidly switch the load to the inverter and a direct current of the stand-by power supply is used to continuously provide power for the load after inversion. When the power supply is restored, the main line is switched to provide power so that a load lamp is ensured not to be in an outage state and not to be off. When the power supply works, efficiency is high; the service life is long and an overload-resistant capability is high.
