Inverter and liquid crystal display including inverter

摘要

An inverter is provided, which includes: a voltage converter that converts a DC voltage from an external device into an AC voltage to drive at least a lamp and includes a primary coil and first and second secondary coils connected in series; a current sensor that senses at least a current flowing in the first or second secondary coil and generate at least a sensing signal based on the sensed at least a current; a feedback signal generator that generates a feedback signal based on the at least a sensing signal from the current sensor; and a controller that controls the voltage converter based on the feedback signal such that a tube current flowing in the at least a lamp keeps substantially constant.
