New magnetic frequency tripler with delta connection suited for high power unit

A magnetic frequency tripler having a new configuration is proposed. The tripler is composed of three series-connected reactor circuits connected in delta. Because a triple frequency current circulates in delta-connection and does not flow into the input line, the input current has very little distortion. Therefore, the tripler is very suited for a high power unit. This paper presents the analyses of the delta circuit as a basic circuit to clarify the characteristics of the tripler. Moreover, the relations between characteristics and circuit constants were examined. The results may be used as a basis for design.
