Matrix converters have wide application such as electrical drives, regulated power supplies and variable voltage sources. Transformers are generally used for isolation of input from the load. Apart from isolation, transformer provides voltage transformation, noise decoupling etc. Conventional isolation transformer is operated at line frequency of 50Hz or 60Hz. Line frequency transformers have lower flux utilization. This makes it heavy, bulky and very expensive part of an electrical converter system. The size and weight of the transformer can be reduced by increasing the saturation flux density of the core material and the maximum allowable temperature rise in the core and windings. Since the saturation flux density is inversely related to frequency, higher frequency of operation reduces the magnetic core size by increasing the flux utilization. So a high frequency isolated power electronic converter provides overall size and cost advantage over a line frequency transformer. This kind of small high frequency isolated power converters are called PETs. One matrix converter operates as AC/AC converter in power electronic transformer. The designed power electronic transformer performs typical functions and has advantages such as power factor correction, voltage sag and swell elimination, voltage flicker reduction and protection capability in fault situations. The proposed power electronic transformer has been modeled using MATLAB/SIMULINK and Power quality .
