This paper proposes a novel power electronic application, which is an IGBT-based frequency converter that performs the function of both cycloconverter and cycloinverter by changing the 2-b input parameter. It finds its application in speed control of induction motor, induction heating, fluorescent lighting, ballast, high-frequency power supplies, and so many other applications. A methodology is developed...
Trapezoidal modulation technique has been applied in AC to AC converter to reduce harmonics in the output. Both step up and step down operation of the converter has been studied for different output frequencies. Simulation results are shown for single-phase to single-phase converter configuration using the software SIMULINK. Minimum total harmonic distortion in the output has been found to be 5% for...
