Abstract
An uninterruptible power supply (UPS) includes a rectifier, a buck converter, a solar energy module, a boost converter, a controller, and a power distribution unit (PDU). The solar energy module receives solar energy and converts the solar energy to a first DC voltage. The controller compares the first DC voltage with a preset voltage, and outputs a control signal to turn the boost converter on or off. When the boost converter is turned off, the rectifier receives an AC voltage from the AC power source and converts this to a rectified DC voltage which is output to the buck converter. When the boost converter is turned on, the boost converter converts the first DC voltage to a second DC voltage. The buck converter converts the rectified DC voltage or the first DC voltage to a working DC voltage and outputs to a power supply unit through the PDU.
