   Multi-Modular Multi-Level PWM Converter Systems
By Vassilios G Agelidis; W. W.L. Keerthipala; William B. Lawrance [View]
[Download]

Abstract: Progress in manufacturing solid state devices with high-voltage and high-current ratings promises more power electronic converter applications in high power systems. On the other hand, such devices when used to build multi-level converters could deliver higher power handling capabilities at converter level. Series andlor parallel connected multilevel converter modules could further increase the power level being controlled by the overall system. In this paper, multi-modular multi-level converter systems are discussed It is revealed that at low carrier frequency range, and for a system of 6-module 5-level converters in parallel, pulsewidth modulation (PWM) results in higher total harmonic distortion (THD) of the line-line voltage output waveform when compared with the fundamental carrier frequency phase-shift controlled counterpart.

Abstract: The simulation of the magnetic shielding in a high current environment is discussed. Basic shielding theory and results from numerical calculations based on 3D-FEM are presented. According to simulations a 6 mm thick rectangular aluminium shielding provides 48 dB shielding.

   Vector Current Controlled Voltage Source Converter - Deadbeat Control and Saturation Strategies
By Rolf Ottersten; Jan Svensson [View]
[Download]

Abstract: This paper presents a VSC connected to a grid with software specially designed for limited control voltage. The VSC uses a deadbeat vector current controller. The paper deals with limiting reference voltage, integrator windup and delay time compensation. Simulations and experimental verifications of the proposed controller are included.
