The present invention relates to a control device and control method for an LLC resonant converter. The device includes: a converter including a plurality of switching elements connected to an input terminal and forming a bridge circuit and capable of switching topology between a full bridge type and a half bridge type; and a control unit for detecting a charge measurement value of a battery charged by receiving power by the converter and switching the topology of the converter based on the charge measurement value. By switching the topology of the converter depending on the charge measurement value of the battery and charging the battery, the LLC resonant converter can be controlled at an optimized frequency, efficiency is increased, and cost reduction is achieved.
