Stability Analysis of a Matrix Converter Drive: Effects of Input Filter Type and the Voltage Fed to the Modulation Algorithm
The matrix converter instability can cause a substantial distortion in the input currents and voltages which leads to the malfunction of the converter. This paper deals with the effects of input filter type, grid inductance, voltage fed to the modulation algorithm and the synchronous rotating digital filter time constant on the stability and performance of the matrix converter. The studies are ...
متن کاملModulation and Control Techniques of Matrix Converter
The Matrix converter is a forced commutated Cyclo-converter with an array of controlled semi conductor switches that connects directly the three phase source to the three phase load. The matrix converter is a direct AC-AC Converter. It has no limit on output frequency due to the fact that it uses semiconductor switches with controlled turn-off capability. The simultaneous commutation of control...
متن کاملPS 2-49 : Six Step Modulation of Matrix Converter with Increased Voltage Transfer Ratio
Conventional modulation strategies for matrix converters based on trigonometric transformations and space vector techniques have their voltage transfer capability limited at about 0.866 p.u. This leads to a derating of motor capability by 25% in the realization of variable frequency drives using off-the-shelf line-fed motors, or requires custom designed motors for operation at reduced voltage. ...
متن کاملNovel Modulation Method for Multidirectional Matrix Converter
This study presents a new modulation method for multidirectional matrix converter (MDMC), based on the direct duty ratio pulse width modulation (DDPWM). In this study, a new structure of MDMC has been proposed to control the power flow direction through the stand-alone battery based system and hybrid vehicle. The modulation method acts based on the average voltage over one switching period conc...
متن کاملComparison of Three Phase Voltage Back to Back Converter and Matrix Converter
This paper presents a comparative evaluation of three phase Voltage Back to Back Converter (VBBC) and three phase Matrix Converter (MC)fed Induction Motor (IM) drive. These two topologies are developed using Space Vector Modulation (SVM) technique and simulated in MATLAB/SIMULINK. Both the topologies are functionally equivalent in terms of input power quality and energy regeneration capabilitie...
