Abstract :
The paper deals with a high power LCCL DC-DC multiresonant converter power supply for telecommunication equipment. The multiresonant concept is here adopted for soft ZVS commutation benefits and switching frequency increase. The involved theoretical analysis and design of such power circuits are tied to the working mode multiplicity and the validity field of power converter behavior in the frequency domain. Multiresonance leads to an over second order system, so the system working conditions study becomes more difficult. The major specifications of the present study are total definition and control of full load and no-load conditions. These working conditions must be obtained without any change of the power converter switching principle (ZVS), for the whole predefined frequency range
