CASCADED H-BRIDGE MULTI LEVEL CONVERTER POWER BALANCE ANALYSIS BY DC LINK VOLTAGES
No full textMulti-level converters have tremendous applications in the power industry and specially cascaded H-bridge (CHB) converters have a vital role in high power applications. They present a new set of features that are well suited for real and reactive power compensation. The distinctive feature of the multilevel inverters is to provide high switching frequencies with low switching losses. In this paper, power balance analysis of single phase cascaded H bridge converter is presented. Power delivering from source to load or load to grid is analyzed by required ac output voltage and from de link voltages. Detailed power balance analysis of this converter has been carried out using MATLAB/SIMULINK and simulation results are shown
FIELD-ORIENTED CONTROL OF PERMANENT MAGNET SYNCHRONOUS MOTOR DRIVE SYSTEM USING MATRIX CONVERTER
Get PDFIn this paper a Field-Oriented Control of permanent magnet synchronous motor (PMSM) drive system using adapted hysteresis current control based on matrix converter is presented. The matrix converter is an arrangement of controlled semiconductor switches that connects directly the three-phase source to the three-phase load. This converter has several attractive features that have been research in the last two decades. To increase use of input voltage assets, input voltages are split into 12 divisions within one cycle. A adapted current controller collected of two nested current hysteresis control is evaluate in details. According to the outputs of current controller and division of input voltages, a proper input voltage must be selected to increase or decrease output current of matrix converter. The division table is evaluate and moderately deduced. Finally, simulation system is designed. Simulating results illustrate that Field-Oriented Control of PMSM drive system using adapted hysteresis current control based on matrix converter has the quality of practicability and efficiency, which brings out theoretical fundamentals of experimentation
