#### Abstract

*This article formulates the new unified interpretation of the analysis of electromagnetic processes in the autonomous (usually resonant) inverters with power circuits having a serial RLC configuration either with or without free wheeling diodes. The investigation starts with clarifying the parameters of the inverter circuit by bringing the fourth order power network into such of a second order in a normalized form. On this basis the novel compendious relationships between the most important internal inverter parameters are given. A MATLAB program calculates and displays the frequency characteristics of both types of inverters and simulates their steady state. The results from characteristics and simulation confirm each other in many ways. They were also proved experimentally. The whole processed information helps better understanding and organizing intelligent design, measurement and control of the inverters for technological applications (induction heating).*
