| 摘 要： | 随着飞行器和航天器上电能需求的增大,在航空航天电源系统中,一体化起动/发电机(ISG)得到了广泛应用。出于可靠性要求,通常采用不控整流来支撑直流母线。而由于电机电枢阻抗的存在,在负载变动时其供电电压会发生跌落。针对该跌落现象,提出了两种电压补偿方案,分别利用电压源型逆变器和移相全桥DC/DC变换器,分别从交流侧和直流侧对供电电压进行补偿。分析了补偿机理并设计了控制系统,分别对其搭建了实验平台。实验结果验证了两种补偿方法的有效性和供电的可靠性,并对两种方法的特点进行了比较。

| Abstract: | With the increase in the electricity demand on aircraft and spacecraft, integrated starter/generator (ISG) has been widely used in aerospace and astronautic power systems. For the sake of reliability, diode bridge rectifier is commonly used to support the direct current (DC) bus. However, because of the armature impedance of the ISG, the supply voltage will drop when the load fluctuates. In order to solve such problems, in this paper, two voltage compensation schemes are proposed, i.e., using the voltage source inverter to compensate the supply voltage from the alternating current (AC) side and using the phase-shifted full bridge DC/DC converter to compensate the supply voltage from the DC side. The compensation mechanisms are analyzed, the control systems are designed, and experimental platforms are set up, respectively. The experimental results validate the availability and power supply reliability of these two proposed schemes, and the characteristics of them are also compared. |
