| Abstract: | A MPPT（Maximum Power Point Tracking） unregulated bus electrical power system topology for space application and its control strategy are presented. The equivalent circuit mod- els of the solar array sources and the loads in two-domain control modes are built separately. The small-signal equivalent analysis method and solving eigenvalues of state space equations method are adopted to analyze the system stability. Some conclusions on increasing the system stability are obtained, which could be referred for applying the MPPT control technology to the future space electrical power system design. |
