The aeronautical active power filter (AAPF) is an advanced solution in resolving the power quality problems of aircraft electrical power systems, and modular construction design plays an important role in improving the flexibility, maintainability and reliability of the aeronautical active power filter system. First, this paper studies a modular aeronautical active power filter which is based on the H-bridge modular circuit. The main circuit topology of the modular aeronautical active power filter is described in a physical structure and a mathematical model. A carrier hybrid pulse width modulation (CH-PWM) colligating the characteristics of carrier phase shift pulse width modulation and carrier disposition pulse width modulation is analyzed. Second, by comparing the power loss of the different main circuit solutions, a suitable topology is selected and its corresponding control strategy is given. Finally, simulation and experiment are performed to verify the theoretical analysis. The results show that the harmonic and reactive components produced by the typical nonlinear load can be compensated effectively by the modular aeronautical active power filter, and the total harmonic distortions (THD) of three-phase source currents are below 5%. Thus, a good compensation performance is achieved by the proposed scheme.
