Problems solved by technology
[0008] One problem with dual power systems is that it is usually not possible to charge the batteries in the UPS in bypass mode, and usually at least some of the batteries are draining while the power supply is providing input power at input 2

Methods and apparatus for providing uninterruptible power are provided by aspects of the invention. One aspect is more particularly directed to an uninterruptible power supply for providing power to a load. The uninterruptible power supply includes an input to receive input power, an output to provide output power, an input power circuit coupled to the input and having a DC output that provides DC power having a first DC voltage level, a capacitor having a first end coupled to the DC output of the input power circuit and having a second end, a back-up power source coupled to the input power circuit, an output power circuit coupled to the DC output of the input power circuit and to the output of the uninterruptible power supply to provide the output power, and a capacitor discharge circuit coupled to the first end of the capacitor and the second end of the capacitor and configured in a first mode of operation to discharge a voltage across the capacitor, such that an average discharge current through the discharge circuit is inversely proportional to a voltage across the capacitor for a first range of voltages across the capacitor.
Description
[0001] This application is a divisional application with the application number 200580037560.3 and the invention title "equipment and method for providing uninterrupted power supply" filed on August 30, 2005. Technical field [0002] The present invention relates to a conventional system and method for providing backup power to critical loads. Background technique [0003] The use of uninterruptible power supply systems (UPS) to provide electrical energy to critical loads is well known. The uninterruptible power supply systems that people know include online UPS and offline UPS. Once the main power source of AC power is interrupted, in addition to the backup AC power, the online UPS provides AC power in good condition. Once the main power source of AC power is interrupted, the offline UPS obviously does not provide conditionally limited input AC power, but provides backup AC power. Figure 1 shows a block diagram of one type of online UPS10. Other online UPSs are described in U....
