Design and Analysis of Three-Phase Reversible High-Power-Factor Correction Based on Predictive Current Controller

A predictive current control for three-phase PWM rectifiers is proposed to simplify the design of the current loop with less memory and interrupt resource occupation in a digital signal processor. Together with the decomposition-matrix method, the total algorithm can be completed with only one timer and its underflow interrupt subroutine. The predictive current controller helps to design the voltage regulator and make the input currents track the input voltages so well that high power factor is achieved. Finally, the experimental results are given to verify the proposed predictive current control.
