Odd Integer Magnetic Frequency Multipliers

A mathematical analysis of odd integer frequency multiplication is presented in this paper. Experimental examples of a 300 watt, 400-2,000 cps tripler and a 3 watt, 400-2,000 cps quintupler are discussed. Output wave forms are shown for multipliers employing two types of core materials. The improved circuitry and appropriate selection of magetic materials as employed in today's magnetic frequency multipliers make the generation of power in the 400-2,000 cps range simple and reliable, and such that efficiencies in the order of 80-90 per cent are possible. In addition, the features of space conservation and power economy can be obtained.
