Abstract: This work presents a comparison of three different modulation techniques applied to modular multilevel converters (MMCs). The three modulation strategies studied in this paper are the phase-shifted sinusoidal pulse width modulation (PS-SPWM), the space-vector modulation (SVM) and the nearest level modulation (NLM). This paper focuses on analysing the particularities and implementation...

Indirect Field Oriented Control (IFOC) is known to produce high performance in induction Motor (IM) drives by decoupling rotor flux and torque producing current components of stator current. The decoupling control between the rotor flux and the torque is no longer achieved in terms of stator current components this paper introduces a decoupled rotor flux and torque control based on the magnetiz...

Space Vector Modulation (SVM) is an alternative method to the conventional, sinusoidal PWM for control of highpower converters. It is known for its higher utilization of the dcbus voltage as well as being readily available for digital implementation. This paper presents the SVM method and a number of its variations, which are implemented in a digital transient simulation program (PSCAD/EMTDC). ...
