Abstract:
In order to overcome the destruction of the electrical network disturbance to the current collector, at present
UPS is widely used as a sensitive power supply. How to eliminate the disturbance of the influence which creates to the
current collector, provide the pure power source for the current collector, is a problem which each UPS manufacturer
faces. The method of enhancing the power input factor in the digitized UPS is introduced. By controlling the input current
profile, the power factor approximates 1, the total harmonic component reduces greatly. |
