An Indirect Matrix Converter with Unity Voltage Transfer Ratio for Ac To Ac Conversion

S.MUTHARASI, G.VARATHAN

In this project, a three phase indirect matrix converter (MC) is proposed, which can able to generate three-phase ac output voltage with variable magnitudes and frequencies from a fixed three-phase ac power supply. It provides sinusoidal input and output current with bidirectional power flow. Moreover, it allows high reliability, a long life-time, as well as a compact design due to the absence of a bulky electrolytic capacitor. The voltage transfers ratio is limited to less than one in conventional IMC. This problem is overcome by AC boosting function in the proposed one. The proposed topology is simulated using MATLAB/Simulink package and implemented using MOSFET with ATmega16 controller. The simulation and implementation result shows the performance of the proposed converter.
