The study made in this paper concerns the use of the direct power control (DPC) technique and the fuzzy logic theory to control a pulse width modulation (PWM) rectifier. These strategies are used to eliminate harmonics currents and consequently to reduce total harmonic distortion (THD) of the line current and improve the power factor. The DPC principle is based on the control of instantaneous a...

Despite its many advantages, the conventional direct power control (DPC) of shunt active power filters (SAPF) poses some problems.

In this paper, a direct power control (DPC) strategies have been investigated in order to control a high power AC/DC converter with time variable load. This converter is composed of a three level three phase neutral point clamped (NPC) converter as rectifier and an H-bridge four quadrant current control converter. In the high power application, controller not only must adjust the desire outputs...
