| 摘要 |
The present invention relates to a battery-linked high efficiency uninterruptible direct current (DC) power supplier comprising a transformer, a first rectifying part, a second rectifying part, an anode conversion part, a cathode conversion part and a battery. The transformer is provided with external DC three-phase power, divides the power into first DC power and second DC power, which have a phase difference, to be transmitted to the first rectifying part and the second rectifying part, respectively. The first rectifying part receives first alternating current (AC) power from the transformer and rectifies the first AC power with the first DC power to be transmitted to the anode conversion part. The second rectifying part receives second AC power from the transformer and rectifies the AC power with the second DC power to be transmitted to the cathode conversion part. The anode conversion part receives the first DC power from the first rectifying part and controls the first DC power with a preset anode value to be transmitted to an output end. The cathode conversion part receives the second DC power from the second rectifying part and controls the second DC power with a preset cathode value to be transmitted to the output end. The battery charges the DC power controlled by the anode conversion part and the cathode conversion part. |
