Abstract：The 270V high-voltage DC grid is a kind of advance aircraft power systems. However, the low frequency ripple current in the main bus will affect on the grid voltage ripple so that it should be eliminated. The DC active filter is proposed to inhibit the low frequency ripple current in the DC grid. As its compensation performance is not influenced by system parameters and loads, the aeronautic DC-APF has a good prospect. Several topologies of DC-APF are described briefly. One with high reliability and low loss is adopted as the main circuit of the aeronautic DC-APF and its operation principle is analyzed. The control strategy of the aeronautic DC-APF is introduced in detail. The control system model is built and the system performances under different parameters are compared. The best control parameters are got with the analysis. Finally, simulation and experiment results verify the feasibility of the aeronautic DC-APF.
