Comparative Analysis Between LLC and LCC DC-DC Resonant Converter for High Voltage Applications

Ritu Sharma; Amol Barve

The aim of this paper is do comparative study between LLC and LCC DC-DC resonant converter for high voltage applications, the two most promising topologies of this converter class are presented and compared in this paper. LCC and LLC resonant converters can achieve both high efficiency and wide input voltage range capability because of its voltage gain characteristics and small switching loss. It is shown that the Different combination of series-parallel resonant converter, which takes the desirable characteristics of the pure series and the pure parallel converter, removes the main disadvantages of those two converters. The proposed circuit of the bridge LLC and LCC resonant converter with 48V output voltage at 12A output current is built to verify the design criteria for the resonant tank.
