The field of soft conversion from one form to another has always been an area of continuous development. However, the recent developments are endorsed to exploring efficient means of single stage AC-AC conversion. Eliminating the energy loss involved in two stage AC-AC conversion has been the focal point for researchers these days. Thus, the present study is devoted to presents the most wanted know-how about the salient design features of Matrix Converter (MC), which provides the straight forward technique for converting fixed frequency at the input to variable frequency at the output. In the present study the simplified design of the single stage AC-AC converter is implemented in MATLAB using bidirectional ideal switches. It is not intended in this study just to list out various works done so for related with application areas of such converter but to bring forth the straight forward control and simulation results of the designed model, which is much needed and constitutes the interest area for researchers. The present simple yet formidable study establishes the brevity of fundamental concept representing the simplified design and its potential application in straight forward control of VFD's and Wind Energy Conversion System. The study first exhibits the design of frequency changer and then the model is used to control the speed of induction motor for 100 HZ and 25 HZ output frequencies. Results for change in frequency and variations in speed according to change in frequency have been obtained by simulating the model through MATLAB/simulink software. The waveforms of changed frequencies and varied speed generated by simulink confirm the results anticipated at design stage.
