dc.description.abstract | This thesis proposes a method for the optimization of a LLC resonant converter in
order to achieve maximum e ciency for a desired load. The novelty of this converter
is the usage of GaN switching devices instead of Si MOSFETs. The prototype is
converting 600 V from the input to a nominal output voltage of 75.6 V, with a
maximum output power of 5.2 kW.
First, an initial design is made without using any optimization process to calculate
its e ciency. The losses taken into consideration are the core and copper losses
generated by the inductors, the switching and conduction losses coming from the GaN
switches, plus the losses generated by the recti er diodes. Afterwards, an optimization
algorithm is implemented, which consists of an iterative solver, to determine the
optimal design of the inductors which were causing the majority of the losses in the
initial design. Maximum e ciency value of 98.6% has been achieved for the optimized
converter. | spa |
