Uninterruptible power operating apparatus

An uninterruptible power operating apparatus electrically connected between an AC power source and a load, and receiving a first AC electric energy outputted from the AC power source, the uninterruptible power operating apparatus comprising:

• an energy storage element configured to provide a first DC electric energy;
• a charging circuit configured to receive and convert the first AC electric energy to charge the energy storage element when the AC power source outputs power normally;
• a DC/DC converting circuit having an input end and an output end, wherein the DC/DC converting circuit is electrically connected with the energy storage element through the input end thereof, and configured to convert the first DC electric energy to a second DC electric energy when the power outputted from the AC power source is interrupted or abnormal;
• a driving circuit comprising a rectifier circuit, a first connection end, a second connection end and an output end, wherein the driving circuit is electrically connected with the AC power source through the first connection end thereof, and electrically connected with the load through the output end thereof, wherein a voltage of the second connection end thereof is corresponding to a voltage of the first connection end thereof, wherein an input end of the rectifier circuit is electrically connected with the first connection end of the driving circuit, an output end of the rectifier circuit is electrically connected with the second connection end of the driving circuit, and the rectifier circuit is configured to convert the first AC electric energy to a third DC electric energy;
• a first DC/AC converting circuit having an input end and an output end, wherein the first DC/AC converting circuit is electrically connected with the second connection end of the driving circuit through the input end thereof, and electrically connected with a DC/AC driving element integration of the load through the output end thereof;
• and
• a switching element having a first end and a second end, wherein the switching element is electrically connected with the output end of the DC/DC converting circuit with the first end thereof, and electrically connected with the second connection end of the driving circuit and the input end of the first DC/AC converting circuit with the second end thereof,
• wherein when the AC power source outputs power normally, the switching element is turned off, the first connection end of the driving circuit receives the first AC electric energy, the driving circuit converts the first AC electric energy to an output electric energy for driving the load, and the first DC/AC converting circuit receives the third DC electric energy through the second connection end of the driving circuit, and
• wherein when the power outputted from the AC power source is interrupted or abnormal, the switching element is turned on, the second connection end of the driving circuit receives the second DC electric energy through the second end of the switching element, the driving circuit converts the second DC electric energy to the output electric energy for driving the load, and the first DC/AC converting circuit receives the second DC electric energy through the output end of the DC/DC converting circuit.
