Abstract

With harmonic distortion becoming an ever increasing concern in Variable Speed Drive (VSD) applications, virtually all Drive, manufacturers now consider limi ting the generation of input current harmonics to be an important issue in their designs. This has led us to the introduction of various drives which should give us considerable reduction in the harmonic distortion. In practical application, the three - phas e to three - phase cycloconverter is commonly required to derive a three - phase output from a three - phase input. The most logical method for producing a three - phase output is to use three symmetrical independent dual converters one for each output phase. As in the case of a rectifier or phase controlled converter circuit, from the view point of reducing the external harmonic voltages and current to a minimum, the pulse number of the cycloconverter circuit should be as high as possible. Cycloconverters enable conversion of AC power to AC power without any intermediate DC link. They are suitable for running induction and synchronous motors. Depending on their topologies they can drive both single - phase and three - phase motors. This paper simulates the working of an induction motor drive with a three - phase to three - phase Cycloconverter. The simulation was carried out using MATLAB - Simulink.
