Abstract
A method for controlling an LLC resonance converter controls a converter through the steps of detecting parameter values related to operation of the converter, determining a switching duty of the converter on the basis of the detected parameter values, and controlling the converter with the determined switching duty to improve nonlinearity of a gain curve of the converter, thereby reducing output current ripples and achieving low-gain output.
