Direct Power Control of PWM Three-Phase Rectifier Using the Predictive Method: Aims to Reduce THD

In this paper, direct control of predictive power for three-phase rectifier using pulse width modulation is presented. For this purpose, direct power control is based on strategy of predictive control to achieve simultaneous control of active & reactive power of converter. To achieve this goal at the beginning of each period the switching average voltage vector of the rectifier which makes possible to zero the error of active& reactive power tracking. Also, at the end of the switching period voltage vectors are calculated by the predictive control algorithm based on the deadbeat control method. As a result, with usage of PWM, the pulses which are required for the rectifier switches are produced.
