Research on the Three-phase Voltage Aviation Rectifier Based on Neural Network PID Control

Aimed to the selection of the PID parameters are very difficult in the rectifier design, and can’t realize the online self-turning function of the PID parameters, the three phase voltage source PWM aviation rectifier based on neural network PID control is designed in this paper. This paper analyzes the principle of the voltage source PWM rectifier based on traditional SVPWM, and improves the control algorithm, and completes the hardware design. In addition, the control algorithm, and the circuit are verified through actual experiments. In this rectifier, the PID parameters can realize the function of the online self-turning. The experimental results show that the three-phase PWM rectifier based on neural network control can decrease the harmonic distortion and the power factor reaches to 0.991, which can supply help for the design of the three-phase voltage high power factor aviation rectifier
