Nonlinear reactance harmonic generation by multiple conversion process.

Abstract

The merits of using multiple conversion processes or modes in practical nonlinear reactance harmonic generators to increase conversion efficiency and power transfer are investigated. In normal operation of harmonic generators only two frequencies are present, the fundamental and the desired harmonic frequency. In the multiple conversion process other frequencies are also present and are terminated in idler circuits. A Hamiltonian analysis of the multiple conversion process due to Dr. Peter Sturrock, Varlan Associates Consultant, is presented. The experimental work emphasizes the principles of multiple conversion. It shows conclusively that for the third harmonic generator circuit considered -- using square law nonlinear reactance elements -- the conversion efficiency and power transfer are increased. This work also shows that multiple frequency output is feasible.
