Study on the Characteristic of Sensitive Load under Voltage Sags

Abstract:

In this paper, the characteristics of AC/DC converter under single-phase voltage sags and three-phase voltage sags are simulated with Matlab emulator. The simulation results show that effects on rectifier equipment under three-phase voltage sags are more serious than those under single-phase voltage sags. The flat wave capacitance plays an important role in voltage sensitivity of sensitive loads. In practice, the capacitance of flat wave capacitor is chosen according to the power supply and load requirements so as to realize the best balance of performance and price.
