The dual power supply system is widely used in our daily life. When power instantaneously switched between the main power and the stand-by power supply, the voltage fluctuations had the varying degree influence on machines. Based on the principle of correlation coefficient of two waveforms and instantaneous reactive power theory, the dual-power supply automatic and instantaneous switching device without disturbance is provided in this paper. The equipment could identify and isolate the broken-down power source in 5ms. At the same time, power supply keeps continuous meeting the requirements of power quality without voltage drop.
