In this paper full bridge LLC resonant converter is
discussed and its design procedure also presented. In this
project work we successfully designed full bridge LLC
resonant converter with the specification
Po=2.4KW,Vo=400V,Vin=72V efficiency =95%. Prototype
of designed LLC resonant converter is realized. But due to
the difficulties in adjusting the value of resonant inductor
we did not use the principle of integrated magnetics. So in
order to enjoy all the advantages of LLC resonant
converter it is recommended to realize the integrated
magnetic structure of the transformer. Various tests are conducted. From the test results various characteristics of
LLC resonant converter were studied.
