Performance and High Robustness DPC for PWM Rectifier under Unstable Direct Voltage Bus

M.S. Djebbar, H. Benalla


This paper proposes a strategy de controlling a static AC/DC converter based on direct power control (DPC). The instantaneous active and reactive power   is controlled in such a way to ensure the PWM rectifier with a sinusoidal current absorption. This control has proven effective in terms of reduction of total harmonic distortion (THD) of current absorbed. Offers a good control of active and reactive power with an operation   at unitary power factor. The test of robustness carried out and the results have proven DPC good performance with strong possibility of  de integrate it into the field of high voltage and high power as electric traction.
