Abstract: An aeronautical variablespeed constantfrequency AC power supply system based on nineswitch converter was presented, the control method was divided into inputside current compensation control and outputside voltage compensation control, through which can reach the goal of aeronautical variablespeed constantfrequency power supply systems requirements that the input side of the current waveform is sinusoidal, and the output voltages amplitude, frequency is respectively 115 V, 400 Hz. Put forward a voltage vector control method which can reduce the switching times of the nineswitch converter. Then the simulation analysis of the control model was carried out, and the results showed that the nineswitch type aeronautical variablespeed constantfrequency AC power system has good dynamic performance under the voltage vector control.
