A stand-by uninterruptible power supply which provides for extended backup time and/or an increase in power rating for stand-by power supply applications. The uninterruptible power supply also has a waveshape circuit for rating the power capacity of the supply. The waveshape circuit provides a more effective way of rating the capacity of the power supply so that different supplies may be easily compared with little confusion.
