About generation of the third harmonica of self-oscillations in Hartley and Meiner's schemes

For modeling of self-oscillations in the generator with autotransformer communication the numerical and analytical method which is based on representation of self-oscillatory system in the form of set of oscillators of the main frequency and its harmonicas is offered. The leading oscillator generates strictly monochromatic self-oscillations in discrete time and excites the compelled fluctuations of oscillators of the highest harmonicas. The main attention is paid to generation of the third harmonica in schemes with transformer and autotransformer communications. It is shown that the offered method of modeling allows to give comparative estimates of amplitudes of harmonious components of a spectrum of self-oscillations.
