Abstract
A phase-cut dimming control system according to the embodiment includes a phase angle detector configured to detect a phase angle of an input voltage generated by phase-cut dimming, a feedback signal generator configured to generate a first reference signal corresponding to the detected phase angle, and generate an initial feedback signal based on a detection signal corresponding to power supplied to a load and the first reference signal, a feedback signal modulator configured to modulate the initial feedback signal and generate a feedback signal, a power transmission controller configured to generate a control signal which controls power transmission according to the feedback signal, and a power transmission circuit configured to transmit power to the load according to the control signal.
