This work proposes a DTC-SVM control algorithm based on Stator coordinate transformation to control an induction machine fed by a three level Neutral point clamped matrix converter. The algorithm is simulated on Matlab Simulink to verify its performance. It gives good performance in general. The results are discussed and a study of the effect of the variation of stator resistance is proposed also.
This paper presents a proposed control of a Wind Energy Conversion System (WECS) with active filtering function for non linear conditions. The Rotor Side Converter (RSC) controls the active and reactive power injected to the grid by the stator of the Doubly Fed Induction Generator (DFIG). The specified control of the Grid Side Converter (GSC) ensures simultaneously the DC link voltage regulation and...
This paper presents a novel space-vector current-control strategy for three-phase neutral-point (NP)-clamped inverters. The main task of this control technique is to force the actual current vector to reach the reference current vector. This original strategy consists in defining three circular hysteresis bands around the error vector. Then, according to the location of this error vector, a selection...
One of the most important drawbacks of the three phase five-level NPC (Neutral Point Clamped) source voltage inverters(VSI) is the Neutral Point balance. As consequence, the capacitor voltages of the input DC voltage of the VSI are not equal. There are different ways to cope with this problem. In this paper, a simple solution that solves this balance is given. It is based on using of four three phase...
