This paper presents a performance comparison of single-phase AC to converter (cycloconverter) and three-phase circuit which divides the input wave frequency (fin) into variable with value output voltage waveform (alternating current) (f, fin/2, fin/3, fin/4, fin/5, fin/6, fin/7, fin/8, fin/9, fin/10. Cycloconvertor switches are built using diode thyristor device. research was conducted by model...
