ABSTRACT:
A transformer designed for 1:N voltage transformation (where 1:N may be any rational number) at high frequencies (such as over 7 megahertz) can achieve acceptable frequency response and attendant improved values of signal attenuation and signal distortion by physically separating two or more sets of electrically tightly coupled windings and connecting one winding of different sets in parallel and the other winding of the same sets in series. This interconnection of windings to achieve a 1:N transformation ratio reduces the negative effects of the interwinding capacitance thereby providing the improved frequency response.
