摘要：The paper develops a functional model for the Alternating Current (AC) Solid State Power Controller (SSPC) based on mixed signal state machine. State transition and impedance variation rules are obtained by analyzing the working modes of the AC SSPC. The model defines three stable states, four intermediate transition states and eleven transition functions to imitate the impedance variations of AC SSPCs during ON/OFF state, zero voltage switch-on, zero current switch-off, and switch-off after short fault. The model considers two switch-off ways for the AC SSPC with short faults: instant switch-off, by which the fault current is instantly reduced to zero in a linear way; and zero current switch-off. The model is implemented by the mixed signal state machine modeling tool (StateAMS) in Saber. Accuracy of the model is verified by configuring the model according to the test results of two AC SSPCs. Speed test results show that the proposed functional model can significantly improve computation efficiency. © 2017, Press of Chinese Journal of Aeronautics. All right reserved.
