Abstract
An uninterruptible power supply with sine wave AC output and energy recycle function is disclosed. The uninterruptible power supply makes use of a DC/DC converter to boost and convert the DC voltage of a battery set to a full-wave rectified shaped DC voltage. A microcontroller is provided to generate a full-wave rectified shaped DC reference signal to force the DC/DC converter to follow the reference signal for adjusting its output to a full-wave rectified shaped DC voltage. The full-wave rectified shaped DC voltage is converted by an inverter to a sine wave AC voltage for providing uninterruptible power. An energy recycle charger is further provided to recycle redundant energy to the battery set.
