摘要
At least some aspects of the invention are directed to methods and apparatus for controlling an uninterruptible power supply and subsystems of a UPS. A first aspect of the invention is directed to a method of controlling a DC-DC converter (30) having a predetermined maximum peak load current value. The DC-DC converter has first and second outputs to couple to a load (62) with a capacitor (52) coupled across the first and second outputs. The method includes in a first mode of operation charging the capacitor to a predetermined output voltage value and in a second mode of operation providing output current having the maximum peak load current value to a load coupled to the output of the DC-DC converter and a second portion of the output current is provided by discharging the capacitor to a voltage value that is less than the predetermined output voltage value.
