Study on Aerospace Serial MPPT Electrical Power System Stability

摘要：

　　Instability phenomena such as bus voltage fluctuations are occurred in serial MPPT(MaximumPower Point Tracking)electrical power system.To study the system stability,the system equivalent circuit models were built based on a serial MPPT unregulated bus electrical power system topology for space application.The small-signal equivalent analysis method and solving eigenvalues of state space equations method were adopted to perform stability analysis in two-domain control modes separately,from which the key conclusions were obtained.A serial MPPT vunregulated bus electrical power system model was built in MATLAB/SIMULINK,in which some application instance was simulated and the simulation results validated the above conclusions.
