Resumen de Computer simulation of power factor corrected circuits
Rafael García Gil, José Miguel Espi Huerta, Jaime Castelló Moreno
An efficient method for simulating three-phase power factor corrected (PFC) converters, using MATLAB/SIMULINK1, is applied for the education and training of undergraduate students in power electronics. This simulation method requires a previous mathematical analysis of the proposed converter to obtain the SIMULINK commutation model, which allows students to acquire a better knowledge of the circuit. Two PFC rectifiers, i.e. voltage source (VSR) and current source (CSR) rectifiers, are analysed and simulated. Two different PFC controllers are considered: a sinusoidal-PWM (SPWM) controller for the VSR and the space vector modulation (SVM) technique for the CSR. With these SIMULINK models, students can carry design the controller and validate whether or not their closed loop system meets the prescribed performance requirements.
