Multi-element Resonant Topology Based on LCLC Circuit: Theory and Application

摘要

The paper deals with novel of multi-element resonant circuits and its modification and application. Main circuits consist of series LC resonant branches and of parallel LC sinusoidal output filters. Review of multi-element circuits which contains more accumulation tanks is presented. Its mathematical description; design of accumulation elements and simulation experiments are given in main chapters of paper. Furthermore, mainly is focus given for application field and on possibility of its variable use. Multi-element circuits meet the requirements of the current market as are: small value of THD, high power density and very high efficiency. Also, such special circuits manifest inners self-regulation which provides resistance to short circuit. The paper also shows analysis of transient properties too. Base on the selected circuits are suggested control methods. All simulation results are verified by experimental measurement created on physical sample. On the end the paper is discussed the application of this circuits and its possible variable use in industry.
