Abstract
The growing interest in power quality has lead to a variety of devices designed for mitigating power disturbances such as harmonics caused due to different problems. By minimizing the total harmonic distortion the harmonic pollution in the power system will be reduced and power quality will be increased. Matrix converter injects significant and non standard frequency components into power systems. The active filter technology is used to minimize the inductance value. To improve harmonics problem series and shunt active filter is used with matrix converter. A shunt active filter senses the load current and injects a current into the system to compensate current harmonics. A shunt active filter is to be placed in parallel with a load to detect the harmonic current of the load and to inject a harmonic current with the same amplitude of that of the load into the AC system. A series active filter is used to eliminate voltage harmonics produced by the matrix converter. The series converter deals with the input voltage distortions. It injects or receives active power for voltage sag or swell compensation. The proposed approach has been tested and validated on the matrix converter using simulink. The datasheet parameters are included in these models to bring it more close to actual circuit model. Simulated results confirm that the active power filters using series and shunt filter can maintain high performance for matrix converter.
