Mathematical Modeling and Simulation of AC-AC Three Phase Matrix Converter with LC Filter driving Static Resistive Load

During the last two decades, it has been seen that power conversion from one form to another form of energy was a serious issue in power electronics. After the production of power converters such as rectifiers that convert AC-DC, inverters that convert DC-AC, voltage regulators, choppers, and cycloconverters make possible power conversion. In 1980, Venturini presented the concept of the Matrix Converter in power electronics; it consists of bidirectional IGBT switches and can conduct current and block reverse and forward voltage. Nowadays matrix converter is frequently utilized for power conversion because it can convert AC-AC, AC-DC, DC-DC, and DC- AC directly without an energy storage device which results in less complexity and cost. In matrix converters, high switching frequency harmonics are produced due to the switching of converters and need to be minimized. In this paper, an LC filter is employed to mitigate the problem of harmonics at the output of the three-phase matrix converter. A three-phase matrix converter with an LC filter is presented in this paper and the SVM technique is used for the generation of pulses. Simulation results are carried out through MATLAB software.

HIL real-time simulator based 3D-space vector pulse width modulation for performance analysis of 3-phase matrix converter

In this paper, Three Dimensional Space Vector Pulse Width Modulation (3D-SVPWM) is developed to obtain the performance analysis of a 3-phase matrix converter (MC). MC is used to convert 3-phase fixed AC voltage to 3-phase variable AC voltage, which provides superior performance compared to conventional AC to AC converters. The 9-bidirectional power switches in a 3-phase matrix converter are controlled by appropriate gating pulses utilizing 3D-SVPWM. In conventional AC to AC power converters, the common mode voltage is induced across the load terminal, which causes bearing failure and EMI issues and so leads to increased total harmonic distortion (THD). Implementing the 3D-SVPWM approach with the nearest switching state vector (NSV) selection mechanism alleviates these problems. In proposed system, CMV is reduced to 37 V, which is equivalent to a Vdc/8 time of the supplied AC input voltage and THD of 3-phase to 3-phase MC is reduced to 1.12% for output voltage and 2.18% for output current. The output findings of the simulation and real-time simulator are verified using the Matlab Simulink model and the HIL real-time (OPAL-RT) simulator.
