Abstract
The present disclosure relates to an apparatus and a method for controlling an LLC resonance converter. The apparatus includes a converter connected to an input terminal, including a plurality of switching elements constituting a bridge circuit, and enabling a topology change in the form of a full bridge and a half bridge; and a controller detecting a charge measurement value of a battery being charged with a power transferred by the converter, and changing a topology of the converter based on the charge measurement value. Since battery charging is performed by changing the topology of the converter in accordance with the charge measurement value of the battery, the LLC resonance converter can be controlled at an optimized frequency, the efficiency is increased, and cost savings can be achieved.
