| Abstract: | In this paper,the principle of the non-circulative Cycloconverter is presented.A new type zero current detecting circuit is introduced,which has many good features,such as a simple structure,short non-circulative dead time and the elimination of "false" current signal.By anatomizing the problem of the practical using of this kind of detecting circuit,the cause of the fault is found out and the problem-solving method is offered. |
