Abstract:
 A large number of harmonics endanger the power grid and other equipment. In order to solve
this problem,a simplified slide mode model of three-phase active power filters was proposed,and its stability
was proved. The model,according to the characteristics that DC voltage dynamics is much slower
than the current dynamics. The DC voltage was viewed as a constant,and then the model of Active Power
Filter ( APF) only including two independent current equations was decoupled. Asymptotic rate was employed
to design slide mode function in the model. Because the fluctuations in the DC voltage results
mainly from energy exchange with the grid,the model took DC voltage error and error change rate as input
conditions,and PI regulator was used to control the DC voltage with the output regulating signal,the
objective of which is to compensate the model error derived from the decoupled model of APF. Simulation
and test results show that the proposed method not only guarantees the system stability,but also the robustness
when sudden changes of the load happens.
