An intelligent uninterruptible inverting power supply device comprising energy-storage circuit and inverting circuit, sine wave signal generator, storage battery pack control circuit, battery charge/discharge protection circuit, switch circuit group, inverting transformer, and load feedback circuit. The sine wave combines the inverting circuit and the load feedback controls automatically the closed-loop circuit of inverting power. A sine wave signal generator is connected with the battery charge/discharge protection circuit. The storage battery pack control circuit is connected with the battery charge/discharge protection circuit. The sine wave signal generator is further in electrical connection with the switch circuit group and the load feedback circuit. The switch circuit group is in electrical connection with the inverting transformer which in turn is in electrical connection with the load feedback circuit. The utility model has high electric capacity, automatic charge/discharge and over-voltage/low-voltage protection, and automatic adjustment of output power. It can supply higher power output to allow the electric appliances to run normally against the failure of the external power supply.
