Question

Advantages and disavantages of cycloconveter

Answer 1

DisadvantagesThe control circuit becomes complex because there are large numbers of SCRs in the cyclo converter. The power factor of the cyclo converter becomes low for low output voltage. The supply gets short circuited due to failure of commutation circuit. The output frequency of the cyclo converter is 1/3th or 1/2 for reasonable power output and efficiency.AdvantagesThe cyclo converter is a single stage converter therefore its efficiency is very high. The cyclo converter operates on line commutation ( except step up cyclo converter ) therefore extra force commutation components are not required. The power transfer in the cyclo converter is possible from supply to load and vice versa at any power factor.
