Abstract

The paper deals with investigation of electrical properties of resonant converter with LC2L2C2 resonant network. Main circuit of proposed converter consists of two series LC resonant branches and of two parallel LC sinusoidal output filters. First the topology of proposed converter is being described, whereby main focus is given for application field and on possibility of its variable use. After it the computation of resonant elements for given parameters with relevant corrections of LC values targeting optimal Q factor is being shown. Next the parametric simulations for identification of voltage transfer characteristic and working intervals for proper operation of proposed converter has been made. Verification of expected operation, through experimental measurement of resonant converter with LCL2C2 elements were realized. Finally the results of the efficiency performance are shown at the end of the paper, whereby results were compared with the international efficiency standards.
