Abstract
Provided is an uninterruptible power supply for providing a sinusoidal-wave output AC voltage. The uninterruptible power supply is advantageous in terms of a DC/DC converter unit consisted of a plurality of DC/DC converter, in which the input terminals of the DC/DC converters are connected in parallel with each other and the output terminals of the DC/DC converters are connected in series with each other. The output DC voltages of the DC/DC converters are configured to sum up to form a full-wave rectified DC voltage, which can be converted into a sinusoidal-wave output AC voltage by an inverter. Furthermore, the uninterruptible power supply provides an energy recycle converter configured for recycling the redundant energy of the uninterruptible power supply to charge a battery pack.
