Design of Generalized Predictive Controller for T-Type Network Inverter

T-type network inverter is a topology that can realize three-phase output from two single-phase output inverters through transformer. The purpose of this paper is to design the circuit topology and controller to make the inverter output voltage meet. Aviation power requirements. Firstly, the DC power input circuit and transformer structure are designed according to the principle of voltage vector synthesis. Then the controller is designed by state space average modeling method and generalized predictive control method. Finally, the system model is built by MATLAB/Simulink simulation software. The 115V/400Hz three-phase power required to convert 27V DC power to aviation power is realized, which verifies the effectiveness of the design content of this paper.
