   Accurate power loss model of a boost cell in a multiphase converter for phase management
By Valérie DUPE, Bruno JAMMES, Lionel SEGUIER, Corinne ALONSO [View]
[Download]

Abstract: This paper proposes a behavioral model of power losses for multiphase converter that will be used to optimize the efficiency of the converter by dynamically modifying the number of working phases. This simple and accurate model is mainly based on the global power loss for one phase of the converter.

   Energy Balancing of the Modular Multilevel Matrix Converter based on a New Transformed Arm Power Analysis
By Felix KAMMERER, Mario GOMMERINGER, Johannes KOLB, Michael BRAUN [View]
[Download]

Abstract: This paper presents a transformed arm power analysis of the Modular Multilevel Matrix Converter(M3C). It enables the energy balancing in the whole frequency range for high power variable-speeddrive applications. Four balancing directions are identified for the active power exchange between theconverter arms with minimal internal currents. At critical operating points a zero sequence voltage isused. Additionally, the reactive power components can be used to perform a real time calculation ofthe energy pulsation in all four balancing directions to improve the control performance. A low voltageprototype with 5 cells in each of the nine arms has been realized to verify the theoretical analysis.

   Energy Concept-based Nonlinear Stabilization and Control for Modular Multilevel Converters for Voltage Oscillation Reduction
By Ali JAAFAR, Gilbert BERGNA, Jean-Claude VANNIER, Pierre LEFRANC [View]
[Download]

Abstract: The Interconnection and Damping Assignment Passivity-Based Control (IDAPBC) is applied phaseindependently to the Modular Multilevel Converter (MMC) in order to overcome dqo-based controlproblems. In addition, an equilibrium point estimator is proposed to determine the time-varyingequilibrium state of the MMC needed as input for the non-linear controller. This control strategyprovides global robust stabilization of the MMC against variations on both its AC and DC sides.Thecontrol + estimator strategy combines both the state-space and energy dynamics models of the MMC.

   Matrix Converter with a Novel Control Method
By Günter SCHRÖDER, Thomas SCHULTE [View]
[Download]

Abstract: In this paper a new drive control strategy for matrix converters is presented that lowers significantly the harmful common mode voltage. The advanced control method is based on the Direct Torque Control scheme. It is applied exemplarily in this paper by use of a Permanent Magnet Synchronous Machine.
