Abstract To realize effective utilization of renewable energy sources, a novel
polymorphic topology with hybrid control strategy based LLC resonant converter
was analyzed and designed in this paper. By combining the merits of a full bridge
LLC resonant converter, three-level half bridge LLC resonant converter, and variable frequency control mode, the converter realizes an intelligent estimation of
input voltage by automatically changing its internal circuit topology. Under this
control strategy, different input voltages determine different operation modes.
This is achieved in full bridge LLC mode when the input voltage is low. If the
input voltage rises More >
