Modeling and investigating the steady state mode of power inverters for electro technology applications

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. On this basis, generalized models of resonant inverters with and without reverse diodes are proposed. On this basis the novel compendious relationships between the most important internal inverter parameters are given. With these models, various inverter operating modes were investigated to search for optimal parameters with a defined target function. The whole processed information helps for good understanding and for organizing intelligent design, measurement and control of the inverters for technological applications (induction heating).
