Analysis and design of a magnetic frequency multiplier

A magnetic frequency multiplier circuit operating from a 60-cycle-per-second (cps) 3-phase supply and delivering an approximately sinusoidal output at a frequency of 180 cps consisting of three identical nonlinear reactors of Deltamax cores inductively loaded is analyzed and a simple design procedure is outlined. The particular case of triple multiplication is chosen for convenience. The method of analysis may be extended to higher frequencies, either by using higher supply frequency or by using more phases. The power capability of the system depends upon the size of the cores, thus efficient multipliers for any desired power output may be designed.
