Research on how to enhance the Chebyshev DC/DC filter's performance 1

To enhance the response speed of the battery pack testing system, the principle of damping-control algorithm and pole-shifting method are analyzed. There steady characteristic and dynamic response abilities that applied to Chebyshev filter are deduced and compared. Based on the optimized equivalent battery model, The Battery testing system is established by MATLAB7.01 to test the characteristics of the three amended Chebyshev filter. Tests were also carried out to proof the scheme. Researches showed that the pole-shifting method possesses batter combination property.
