Abstract

The paper deals with design analysis, simulation, synthesis and verification of power resonant converter integrated with LCLC filter, HF transformer and rectifier output. The output voltage of LCTLC in the basic AC direct mode is sinusoidal one with harmonic distortion roughly 5% in the whole range of the load with possibility of non-symmetrical control of the converter. A novel detailed analysis of over-loaded rectifying mode with DC output is given, as well as transfer and transient properties analysis, non-linearity including. Simulations based on Matlab/OrCad models confirmed by experimental results of both modes are given in the paper.
