APPARATUS AND METHOD FOR CONTROLLING LLC RESONANCE CONVERTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17696217 titled 'APPARATUS AND METHOD FOR CONTROLLING LLC RESONANCE CONVERTER
Simplified Explanation
The present disclosure describes an apparatus and method for controlling an LLC resonance converter used for charging batteries. The apparatus includes a converter with multiple switching elements that can be configured as a full bridge or a half bridge. A controller is used to detect the charge measurement value of the battery being charged and change the converter's topology based on this value.
- The apparatus includes a converter with multiple switching elements that can be configured as a full bridge or a half bridge.
- A controller is used to detect the charge measurement value of the battery being charged.
- The topology of the converter is changed based on the charge measurement value.
- By changing the topology of the converter according to the charge measurement value, the LLC resonance converter can be controlled at an optimized frequency.
- This optimization increases the efficiency of the converter and leads to cost savings.

Original Abstract Submitted
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.
