摘要：Electrifying the on-board subsystems of aircraft becomes an inevitable process as being faced with the environmental pollution,along with the proposed concept called more electric aircraft(MEA).With the increasing number of on-board power electronic based devices,the distribution system of the aircraft can be regarded as an onboard *** it is known that the load power electronic converters can exhibit constant power load(CPL)characteristics and reduce the system stability,it is necessary to accurately predict and enhance the system stability in designing *** paper firstly analyzes the stability of an on-board DC microgrid with the presence of ***,discusses the reasons behind instability and proposes a control strategy to enhance system ***,the simulation results are worked out to validate the analysis and the effect of the proposed control strategy.
