ANALYSIS OF ELECTROMAGNETIC PROCESSES IN A RESONANT ELECTRIC POWER AMPLIFIER
Abstract
The purpose of this work was to propose and theoretically substantiate the fundamental operability of the reactive power transformer circuit, consisting of two series resonant circuits with an adjustable level of electromagnetic coupling between them. Basic analytical expressions for the characteristics of electromagnetic processes in the circuit of the adopted resonant converter are obtained. It is shown that the maximum possible amplification factor of electric reactive power is proportional to the quality factor of the secondary circuit of the transformer. The reliability of the results obtained is confirmed by the conducted experimental studies. Their results showed that the discrepancies between theoretical estimates and experimental data are rather insignificant, and they can be explained by the influence of external electromagnetic fields (superposition of the fields of the "output" solenoid and the coupling transformer). In general, the results obtained illustrate the real possibilities of multiple amplification of reactive electrical power in the proposed resonant transformer circuit. Further work involves the development and creation of a converter of reactive electrical energy into active energy.
