To solve the problem that the traditional uncontrolled voltage transformation rectifier with diode and&nbsp; load could cause a lot of harmonic and reactive power pollution to the aircraft power grid in the process of nonlinear operation, a voltage and current double closedloop control structure of controllable voltage transformation rectifier was proposed. The mathematical model of the equivalent circuit of the controlled rectifier was established by dq transformation method, and the steadystate operating point of the system was obtained by power flow calculation. The sensitivity of electrical parameters and control parameters to the small disturbance stability of the controlled rectifier near the steadystate operating point was analyzed. The analysis results and simulation results show that the power supply circuit of controlled rectifier has good voltage stabilizing effect. The small signal stability of the system can be significantly improved by decreasing the integral coefficient of the outer loop voltage loop and the daxis proportional coefficient of the inner loop current loop or increasing the proportional coefficient of the outer loop voltage loop and the daxis integral coefficient of the inner loop current loop.
