ELECTRIC OSCILLATIONS PARAMETRIC RESONANCE EXCITATION SWITCHING METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2025 - IPC H02M7/523 

FIELD: electric power engineering.

SUBSTANCE: invention relates to power industry, more specifically to self-contained power supplies, and can be widely used in industry, in household appliances and especially in transport. Commutation method of excitation of parametric resonance of electric oscillations consists in the fact that additional inductance coils and capacitors with various ratings are connected to the main oscillatory circuit by means of thyristors. Electric oscillations parametric resonance excitation switching method implementation device includes the main oscillatory circuit and made in cascade additional inductance coils with the inductance rating, and capacitors with installed ratings, three times greater or less than similar elements of the circuit, installed in a cascade with the possibility of controlling thyristors.

EFFECT: simplification, reduction of weight and overall dimensions, increase of power and reduction of dependence on external sources of electric energy and on the load value; it also leads to increase of power and stabilization of the value of generated energy and reduces electric power drawdown at load change.
