Abstract

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 cyclo-inverter operation for a frequency range of 500 to 750 Hz. During cyclo-converter operation it reduces to 1.2% up to a frequency range of 1 Hz to 16.66 Hz which is generally recommended mode of cyclo-converter.
