Abstract
An uninterruptible power supply (UPS) includes a rectifier, a converter, a first auxiliary power source, and a power distribution unit (PDU). The rectifier receives an alternating current (AC) voltage from an AC power source and converts this to a rectified direct current (DC) voltage which is outputted to the converter. The converter converts the rectified DC voltage to a working voltage and outputs the working voltage to a power supply unit (PSU) through the PDU. The first auxiliary power source outputs a DC voltage to the PSU through the PDU when the AC power source is down.
Claims8
An uninterruptible power supply (UPS) applicable to a power supply unit (PSU) of an electronic device, the UPS comprising:
- an alternating current (AC) power interface connected to an AC power source;
- a rectifier converting an AC voltage received from the AC power interface to a rectified direct current (DC) voltage;
- a converter converting the rectified DC voltage to a working DC voltage according to voltage requirement of the PSU of the electronic device;
- a power distribution unit (PDU) connected to the converter to receive the working DC voltage and output the working DC voltage to the PSU;
- and
- a first auxiliary power source, wherein when the AC power source is down, the first auxiliary power source outputs a voltage to the PSU according to voltage requirement of the PSU of the electronic device through the PDU.
