Abstract: An uninterruptible power operating apparatus includes an energy storage element, a charging circuit, a DC/DC converting circuit, a first DC/AC converting circuit, a driving circuit and a switching element. The DC/DC converting circuit is electrically connected with the energy storage element to convert its first DC energy to a second DC energy. The first DC/AC converting circuit is electrically connected with the DC/DC converting circuit. The driving circuit is electrically connected between an AC power source and a load. The switching element is electrically connected between the DC/DC converting circuit and the driving circuit. When the AC power source outputs power normally, the switching element is turned off, and the driving circuit receives energy from AC power source. When the power outputted from the AC power source is interrupted or abnormal, the switching element is turned on, and the driving circuit receives the second DC energy through the switching element.
