摘要

变频供电系统具有节能、轻便等优点。随着直流配电系统在新型飞机上的应用，直流配电系统将成为未来全电动飞机的重要发展方向。更多的恒频负载将由逆变器由直流母线供电。飞机电力系统运行中会受到较大的信号干扰，对逆变器的性能影响很大。针对这一问题，本文提出了一种基于广义状态空间平均法的12脉冲大信号干扰逆变器模型。通过将广义状态空间平均模型分析结果与状态空间平均和时域仿真结果进行比较，验证了该模型对直流母线配电系统更为准确和有效。

Model of inverter in more electric aircraft based on generalized state space averaging approach

The variable frequency power supply system has advantages of energy saving and light weighting. With its application in the new aircraft, DC distribution system is becoming important direction of more or all electric aircraft in the future. More constant frequency load will be supplied with DC main bus by inverter. Aircraft electric power system operation may suffer from large signal disturbances, which affect the inverter's performance greatly. To address the issue, this paper presents a 12-pulse inverter model for large signal disturbance based on generalized state space averaging method. By comparing generalized state space averaging model analysis result with state space averaging and time domain simulation, it is very verified the model is more accurate and effective for dc main bus power distribution system.
