摘要： The present invention relates to a switching operation control device of a power switch, an LED light emitting device including the same, and a control method thereof. The control device detects a zero crossing time when a voltage at an input end of the power switch becomes a zero voltage, generates a reference signal that is synchronized with the voltage at the input end of the power switch by using the detected zero crossing time, and compensates the generated reference signal with a first voltage that is greater than the zero voltage during a blocking period corresponding to the zero crossing time.
