  "textContent": "A wireless charging for charging a battery by controlling a PFC circuit, a DC-DC converter, and an IPT device sequentially connected, includes: a battery charging controller configured to receive a battery voltage value and a current value of the battery, which are sensed through a battery voltage and current sensor, and generate a charging control signal based on the received voltage value and current value; a PFC controller configured to control switching operations of the PFC so as to adjust a direct-current bus voltage supplied to the DC-DC converter based on the charging control signal, and output a converter operation enable signal; and a converter controller configured to control switching of the DC-DC converter based on the converter operation enable signal and the charging control signal, thereby guaranteeing stable and efficient battery charging regardless of positional errors and matching variations between the transmission and reception coils.",
