Analysis of predictive control for boost converter in power factor correction application

This work presents a boost converter design methodology for active power factor correction, using finite control set model-based predictive control (FCS-MPC) for current control. Moreover, an external proportional integrative (PI) voltage control loop design methodology is explained. This paper also compares the conventional PI current control with MPC current for this application, both in transient load disturbance condition and in steady state different load conditions. The results in rated operation are compared with IEC 61000-3-2 international standard, which establishes limits for current harmonics rms values. The design methodology shows itself effective, with results near to the expected. Both controllers presented advantages and disadvantages, many of them exhaustively discussed in this work.
