The calculation and analysis of starting converter unit is the key technology of starter/generator starting control. The current hysteresis tracking control strategy of direct current/alternating current(DC/AC) main converter is analyzed. The current regulated/voltage limited exciter current generation circuit is calculated. The simulation models are established. Combined with the system model of the three-level synchronous brushless machine under the starting condition, the simulation experiment of starting system is conducted. The results of the simulation show that the starting control system can operate reliably and stably, the DC/AC main converter produces three-phase pulse width modulation(PWM) current accurately, and the output of the excitation current generation circuit satisfies the stator winding excitation requirement of auxiliary exciter. The research of the starting converter unit in the starter/generator dual-function system has reference for the later research of electric starting technology of the main engine of more electric aircraft.
