LLC INTERLEAVED LLC RESONANT CONVERTER AND CONTROL METHOD THEREOF

摘要

The present invention relates to an N converter module including a plurality of switches constituting a full bridge circuit, a resonant inductor, a resonant capacitor and a transformer, and operating in LLC resonance type; And controlling the N converter modules at the same frequency so as to control the switch phase difference (?) Of each converter module so that the deviation of the current output from each converter module falls within an error range, The present invention provides an interleaved LLC resonant converter including a controller for controlling a module phase difference (PHI) of a module within a certain range from (? K / N -? / 2).
